• Extracting the Layout of all the Data Forms from the Relational Database

  - by RahulS

  Today I came across a question from one of our clients that: "what members are used on each data form WITHOUT having to go through the report generated out of our Planning app". We worked with client on this and reached to a simple query. All the form related information is stored in the following tables: HSP_FORM HSP_FORMOBJ_DEF HSP_FORMOBJ_DEF_MBR HSP_FORM_ATTRIBUTES HSP_FORM_CALCS HSP_FORM_DV_CONDITION HSP_FORM_DV_PM_RULE HSP_FORM_DV_RULE HSP_FORM_DV_USER_IN_PM_RULE HSP_FORM_LAYOUT HSP_FORM_MENUS HSP_FORM_VARIABLES If we want to retrieve just the members included, we can concentrate on: HSP_OBJECT to get the Object_ID for form, Object_Type is 7 for forms. (Ex: Select * from HSP_OBJECT where OBJECT_TYPE = 7) HSP_FORMOBJ_DEF Find the OBJDEF_ID for a particular form HSP_FORMOBJ_DEF_MBR Use the above OBJDEF_ID to find the members: Here the Mbr_ID is the Id of the member and Query_Type is the Function like Idesc, Level0 etc and Sequce is you sequence, And the final table we can use is HSP_FORM_LAYOUT: Layout_Type: 0->Pov 1-> Page, 2->Row, 3->Col, DIM_ID is the dimension ID and Ordinal is position. Here is the Query: SELECT HSP_OBJECT.OBJECT_NAME AS 'Form',  HSP_OBJECT_2.OBJECT_NAME AS 'Dimension',  HSP_OBJECT_1.OBJECT_NAME AS 'Member',  HSP_FORMOBJ_DEF_MBR.QUERY_TYPE FROM  <DatabaseName>.dbo.HSP_FORM_LAYOUT HSP_FORM_LAYOUT,  <DatabaseName>.dbo.HSP_FORMOBJ_DEF HSP_FORMOBJ_DEF,  <DatabaseName>.dbo.HSP_FORMOBJ_DEF_MBR HSP_FORMOBJ_DEF_MBR,  <DatabaseName>.dbo.HSP_MEMBER HSP_MEMBER,  <DatabaseName>.dbo.HSP_OBJECT HSP_OBJECT,  <DatabaseName>.dbo.HSP_OBJECT HSP_OBJECT_1,  <DatabaseName>.dbo.HSP_OBJECT HSP_OBJECT_2 WHERE  HSP_OBJECT.OBJECT_ID = HSP_FORMOBJ_DEF.FORM_ID AND  HSP_FORMOBJ_DEF_MBR.OBJDEF_ID = HSP_FORMOBJ_DEF.OBJDEF_ID AND  HSP_MEMBER.MEMBER_ID = HSP_FORMOBJ_DEF_MBR.MBR_ID AND  HSP_OBJECT_1.OBJECT_ID = HSP_MEMBER.MEMBER_ID AND  HSP_OBJECT_2.OBJECT_ID = HSP_MEMBER.DIM_ID AND  HSP_FORM_LAYOUT.DIM_ID = HSP_MEMBER.DIM_ID AND  HSP_FORM_LAYOUT.FORM_ID = HSP_FORMOBJ_DEF.FORM_ID AND  ((HSP_OBJECT.OBJECT_TYPE=7)) ORDER BY HSP_OBJECT.OBJECT_NAME  Concentrate on Test1 data form and Actual Layout of it as follows: Corresponding Query_type for few of the functions: 9  for Idesc, 3  for Ancestors, -9 for ILvl0Des, 8  for Desc, 4  for IAncestors Its just a basic idea you can do lot on the basis of this.

• mongoDB Management Studio

  - by Liam McLennan

  This weekend I have been in Sydney at the MS Web Camp, learning about web application development. At the end of the first day we came up with application ideas and pitched them. My idea was to build a web management application for mongoDB. mongoDB I pitched my idea, put down the microphone, and then someone asked, “what’s mongo?”. Good question. MongoDB is a document database that stores JSON style documents. This is a JSON document for a tweet from twitter: db.tweets.find()[0] { "_id" : ObjectId("4bfe4946cfbfb01420000001"), "created_at" : "Thu, 27 May 2010 10:25:46 +0000", "profile_image_url" : "http://a3.twimg.com/profile_images/600304197/Snapshot_2009-07-26_13-12-43_normal.jpg", "from_user" : "drearyclocks", "text" : "Does anyone know who has better coverage, Optus or Vodafone? Telstra is still too expensive.", "to_user_id" : null, "metadata" : { "result_type" : "recent" }, "id" : { "floatApprox" : 14825648892 }, "geo" : null, "from_user_id" : 6825770, "search_term" : "telstra", "iso_language_code" : "en", "source" : "&lt;a href=&quot;http://www.tweetdeck.com&quot; rel=&quot;nofollow&quot;&gt;TweetDeck&lt;/a&gt;" } A mongodb server can have many databases, each database has many collections (instead of tables) and a collection has many documents (instead of rows). Development Day 2 of the Sydney MS Web Camp was allocated to building our applications. First thing in the morning I identified the stories that I wanted to implement: Scenario: View databases Scenario: View Collections in a database Scenario: View Documents in a Collection Scenario: Delete a Collection Scenario: Delete a Database Scenario: Delete Documents Over the course of the day the team (3.5 developers) implemented all of the planned stories (except ‘delete a database’) and also implemented the following: Scenario: Create Database Scenario: Create Collection Lessons Learned I’m new to MongoDB and in the past I have only accessed it from Ruby (for my hare-brained scheme). When it came to implementing our MongoDB management studio we discovered that their is no official MongoDB driver for .NET. We chose to use NoRM, honestly just because it was the only one I had heard of. NoRM was a challenge. I think it is a fine library but it is focused on mapping strongly typed objects to MongoDB. For our application we had no prior knowledge of the types that would be in the MongoDB database so NoRM was probably a poor choice. Here are some screens (click to enlarge):

• Using multiple diagrams per model in Entity Framework 5.0

  - by nikolaosk

  I have downloaded .Net framework 4.5 and Visual Studio 2012 since it was released to MSDN subscribers on the 15th of August.For people that do not know about that yet please have a look at Jason Zander's excellent blog post .Since then I have been investigating the many new features that have been introduced in this release.In this post I will be looking into theIn order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 20120 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine. I have also installed in my machine SQL Server 2012 developer edition. I have also downloaded and installed AdventureWorksLT2012 database.You can download this database from the codeplex website.   Before I start showcasing the demo I want to say that I strongly believe that Entity Framework is maturing really fast and now at version 5.0 can be used as your data access layer in all your .Net projects.I have posted extensively about Entity Framework in my blog.Please find all the EF related posts here. In this demo I will show you how to split an entity model into multiple diagrams using the new enhanced EF designer. We will not build an application in this demo.Sometimes our model can become too large to edit or view.In earlier versions we could only have one diagram per EDMX file.In EF 5.0 we can split the model into more diagrams.1) Launch VS 2012. Express edition will work fine.2) Create a New Project. From the available templates choose a Web Forms application  3) Add a new item in your project, an ADO.Net Entity Data Model. I have named it AdventureWorksLT.edmx.Then we will create the model from the database and click Next.Create a new connection by specifying the SQL Server instance and the database name and click OK.Then click Next in the wizard.In the next screen of the wizard select all the tables from the database and hit Finish.4) It will take a while for our .edmx diagram to be created. When I select an Entity (e.g Customer) from my diagram and right click on it,a new option appears "Move to new Diagram".Make sure you have the Model Browser window open.Have a look at the picture below 5) When we do that a new diagram is created and our new Entity is moved there.Have a look at the picture below  6) We can also right-click and include the related entities. Have a look at the picture below. 7) When we do that the related entities are copied to the new diagram.Have a look at the picture below  8) Now we can cut (CTRL+X) the entities from Diagram2 and paste them back to Diagram1.9) Finally another great enhancement of the EF 5.0 designer is that you can change colors in the various entities that make up the model.Select the entities you want to change color, then in the Properties window choose the color of your choice. Have a look at the picture below. To recap we have demonstrated how to split your entity model in multiple diagrams which comes handy in EF models that have a large number of entities in them Hope it helps!!!!

• Add SQL Azure database to Azure Web Role and persist data with entity framework code first.

  - by MagnusKarlsson

  In my last post I went for a warts n all approach to set up a web role on Azure. In this post I’ll describe how to add an SQL Azure database to the project. This will be described with an as minimal as possible amount of code and screen dumps. All questions are welcome in the comments area. Please don’t email since questions answered in the comments field is made available to other visitors. As an example we will add a comments section to the site we used in the previous post (Länk här). Steps: 1. Create a Comments entity and then use Scaffolding to set up controller and view, and add ConnectionString to web.config. 2. Create SQL Azure database in Management Portal and link the new database 3. Test it online!   1. Right click Models folder, choose add, choose “class…” . Name the Class Comment. 1.1 Replace the Code in the class with the following: using System.Data.Entity; namespace MvcWebRole1.Models { public class Comment {    public int CommentId { get; set; }    public string Name { get; set; }      public string Content { get; set; } } public class CommentsDb : DbContext { public DbSet<Comment> CommentEntries { get; set; } } } Now Entity Framework can create a database and a table named Comment. Build your project to assert there are no build errors.   1.2 Right click Controllers folder, choose add, choose “class…” . Name the Class CommentController and fill out the values as in the example below.     1.3 Click Add. Visual Studio now creates default View for CRUD operations and a Controller adhering to these and opens them. 1.3 Open Web.config and add the following connectionstring in <connectionStrings> node. <add name="CommentsDb” connectionString="data source=(LocalDB)\v11.0;Integrated Security=SSPI;AttachDbFileName=|DataDirectory|\CommentsDb.mdf;Initial Catalog=CommentsDb;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />   1.4 Save All and press F5 to start the application. 1.5 Go to http://127.0.0.1:81/Comments which will redirect you through CommentsController to the Index View which looks like this:     Click Create new. In the Create-view, add name and content and press Create.   1: // 2: // POST: /Comments/Create 3:  4: [HttpPost] 5: public ActionResult Create(Comment comment) 6: { 7: if (ModelState.IsValid) 8: { 9: db.CommentEntries.Add(comment); 10: db.SaveChanges(); 11: return RedirectToAction("Index"); 12: } 13:  14: return View(comment); 15: } 16:    The default View() is Index so that is the View you will come to. Looking like this: 1: // 2: // GET: /Comments/ 3: 4: public ActionResult Index() 5: { 6: return View(db.CommentEntries.ToList()); 7: } Resulting in the following screen dump(success!):   2. Now, go to the Management portal and Create a new db.   2.1 With the new database created. Click the DB icon in the left most menu. Then click the newly created database. Click DASHBOARD in the top menu. Finally click Connections strings in the right menu to get the connection string we need to add in our web.debug.config file.   2.2 Now, take a copy of the connection String earlier added to the web.config and paste in web.debug.conifg in the connectionstrings node. Replace everything within “ “ in the copied connectionstring with that you got from SQL Azure. You will have something like this:   2.3 Rebuild the application, right click the cloud project and choose “Package…” (if you haven’t set up publishing profile which we will do in our next blog post). Remember to choose the right config file, use debug for staging and release for production so your databases won’t collide. You should see something like this:   2.4 Go to Management Portal and click the Web Services menu, choose your service and click update in the bottom menu.   2.5 Link the newly created database to your application. Click the LINKED RESOURCES in the top menu and then click “Link” in the bottom menu. You should get something like this. 3. Alright then. Under the Dashboard you can find the link to your application. Click it to open it in a browser and then go to ~/Comments to try it out just the way we did locally. Success and end of this story!

• A strong component keeps everything together

  - by Justin Paul-Oracle

  Most of the times you implement a WebCenter Content based system, you require some sort of customization. Sometimes these customizations need a Java class or two, or libraries (for example, the JavaMail API), or Database Objects (like new tables, views, indexes, etc). I have seen that libraries and Database Objects are usually put in place using manual steps. This means that the library jar files are copied to one of the common classes directory (set in the Content CLASSPATH variable) and/or the database scripts are executed manually. I have also seen people place the custom Java classes in the common classes directory. While this may seem like an easy solution, think about a scenario where you need to disable or uninstall the component or if you have to upgrade or migrate the system. You have to keep these manual steps documented and execute them every time you encounter the above scenarios. It is very common that some of these manual steps are missed when you have multiple teams and people working on the system. Here are a few points to ponder upon: Place all your custom Java classes within your component. Create a new directory, say ${COMPONENT_DIR}/classes, and place your code there. You can choose to bundle all your classes into a jar or you can place the entire class directory structure. Add a path entry to the Build Settings so that it is bundled with the component when you build it. You also need to update the Custom Class Path and the Custom Class Path Load Order under the Advanced Build Settings. This will ensure that the system CLASSPATH is updated to add this new directory. Create a new component for any new library that you want to add. Add the appropriate path entries to the Build Settings so that it is bundled with the component when you build it. You also need to update the Custom Class Path, Custom Class Path Load Order and/or the Custom Library Path under the Advanced Build Settings. Enter a comma separated list of features that this component will provide. When you create other components that will use the features exposed by this component, make sure that you specify a dependency to this library component by specifying the comma separated list of features in the Advanced Build Settings. The component wizard allows you to create custom install/uninstall Java code. The wizard will create a install filter class when you check the “Has Install” checkbox on the “Install/Uninstall Settings” tab. Consider using this filter class to create database objects when you install the component and drop the objects when you uninstall the component. If you do a lot of custom component development, consider creating a install/uninstall Java class, which can execute queries defined within the component. To sum up, whenever you write a new custom component, make sure that you bundle everything within the component.

• The most dangerous SQL Script in the world!

  - by DrJohn

  In my last blog entry, I outlined how to automate SQL Server database builds from concatenated SQL Scripts. However, I did not mention how I ensure the database is clean before I rebuild it. Clearly a simple DROP/CREATE DATABASE command would suffice; but you may not have permission to execute such commands, especially in a corporate environment controlled by a centralised DBA team. However, you should at least have database owner permissions on the development database so you can actually do your job! Then you can employ my universal "drop all" script which will clear down your database before you run your SQL Scripts to rebuild all the database objects. Why start with a clean database? During the development process, it is all too easy to leave old objects hanging around in the database which can have unforeseen consequences. For example, when you rename a table you may forget to delete the old table and change all the related views to use the new table. Clearly this will mean an end-user querying the views will get the wrong data and your reputation will take a nose dive as a result! Starting with a clean, empty database and then building all your database objects using SQL Scripts using the technique outlined in my previous blog means you know exactly what you have in your database. The database can then be repopulated using SSIS and bingo; you have a data mart "to go". My universal "drop all" SQL Script To ensure you start with a clean database run my universal "drop all" script which you can download from here: 100_drop_all.zip By using the database catalog views, the script finds and drops all of the following database objects: Foreign key relationships Stored procedures Triggers Database triggers Views Tables Functions Partition schemes Partition functions XML Schema Collections Schemas Types Service broker services Service broker queues Service broker contracts Service broker message types SQLCLR assemblies There are two optional sections to the script: drop users and drop roles. You may use these at your peril, particularly as you may well remove your own permissions! Note that the script has a verbose mode which displays the SQL commands it is executing. This can be switched on by setting @debug=1. Running this script against one of the system databases is certainly not recommended! So I advise you to keep a USE database statement at the top of the file. Good luck and be careful!!

• WSS 3.0 to SharePoint 2010: Tips for delaying the Visual Upgrade

  - by Kelly Jones

  My most recent project has been to migrate a bunch of sites from WSS 3.0 (SharePoint 2007) to SharePoint Server 2010.  The users are currently working with WSS 3.0 and Office 2003, so the new ribbon based UI in 2010 will be completely new.  My client wants to avoid the new SharePoint 2010 look and feel until they’ve had time to train their users, so we’ve been testing the upgrades by keeping them with the 2007 user interface. Permission to perform the Visual Upgrade One of the first things we noticed was the default permissions for who was allowed to switch the UI from 2007 to 2010.  By default, site collection administrators and site owners can do this.  Since we wanted to more tightly control the timing of the new UI, I added a few lines to the PowerShell script that we are using to perform the migration.  This script creates the web application, sets the User Policy, and then does a Mount-SPDatabase to attach the old 2007 content database to the 2010 farm.  I added the following steps after the Mount-SPDatabase step: #Remove the visual upgrade option for site owners # it remains for Site Collection administrators foreach ($sc in $WebApp.Sites){ foreach ($web in $sc.AllWebs){ #Visual Upgrade permissions for the site/subsite (web) $web.UIversionConfigurationEnabled = $false; $web.Update(); } } These script steps loop through each Site Collection in a particular web application ($WebApp) and then it loops through each subsite ($web) in the Site Collection ($sc) and disables the Site Owner’s permission to perform the Visual Upgrade. This is equivalent to going to the Site Collection administrator settings page –> Visual Upgrade and selecting “Hide Visual Upgrade”. Since only IT people have Site Collection administrator privileges, this will allow IT to control the timing of the new 2010 UI rollout. Newly created subsites Our next issue was brought to our attention by SharePoint Joel’s blog post last week (http://www.sharepointjoel.com/Lists/Posts/Post.aspx?ID=524 ).  In it, he lists some updates about the 2010 upgrade, and his fourth point was one that I hadn’t seen yet: 4. If a 2007 upgraded site has not been visually upgraded, the sites created underneath it will look like 2010 sites – While this is something I’ve been aware of, I think many don’t realize how this impacts common look and feel for master pages, and how it impacts good navigation and UI. As well depending on your patch level you may see hanging behavior in the list picker. The site and list creation Silverlight control in Internet Explorer is looking for resources that don’t exist in the galleries in the 2007 site, and hence it continues to spin and spin and eventually time out. The work around is to upgrade to SP1, or use Chrome or Firefox which won’t attempt to render the Silverlight control. When the root site collection is a 2007 site and has it’s set of galleries and the children are 2010 sites there is some strange behavior linked to the way that the galleries work and pull from the parent. Our production SharePoint 2010 Farm has SP1 installed, as well as the December 2011 Cumulative Update, so I think the “hanging behavior” he mentions won’t affect us. However, since we want to control the roll out of the UI, we are concerned that new subsites will have the 2010 look and feel, no matter what the parent site has. Ok, time to dust off my developer skills. I first looked into using feature stapling, but I couldn’t get that to work (although I’m pretty sure I had everything wired up correctly).  Then I stumbled upon SharePoint 2010’s web events – a great way to handle this. Using Visual Studio 2010, I created a new SharePoint project and added a Web Event Receiver: In the Event Receiver class, I used the WebProvisioned method to check if the parent site is a 2007 site (UIVersion = 3), and if so, then set the newly created site to 2007:   /// <summary> /// A site was provisioned. /// </summary> public override void WebProvisioned(SPWebEventProperties properties) { base.WebProvisioned(properties);   try { SPWeb curweb = properties.Web;   if (curweb.ParentWeb != null) {   //check if the parent website has the 2007 look and feel if (curweb.ParentWeb.UIVersion == 3) { //since parent site has 2007 look and feel // we'll apply that look and feel to the current web curweb.UIVersion = 3; curweb.Update(); } } } catch (Exception) { //TODO: Add logging for errors } }   This event is part of a Feature that is scoped to the Site Level (Site Collection).  I added a couple of lines to my migration PowerShell script to activate the Feature for any site collections that we migrate. Plan Going Forward The plan going forward is to perform the visual upgrade after the users for a particular site collection have gone through 2010 training. If we need to do several site collections at once, we’ll use a PowerShell script to loop through each site collection to update the sites to 2010.  If it’s just one or two, we’ll be using the “Update All Sites” button on the Visual Upgrade page for Site Collection Administrators. The custom code for newly created sites won’t need to be changed, since it relies on the UI version of the parent site.  If the parent is 2010, then the new site will look 2010.

This knowledge document outlines a procedure to reliably measure lag between source and target systems through the use of 'heartbeat' tables. The basic idea is to have a table on the source system that gets updated at a predetermined interval. In your capture processes you would capture the update from the heartbeat table. Using tokens you would add some additional information to the heartbeat record to be able to tell which extract process was capturing the update. This additional information would be used downstream to calculate the real lag time between the source and target systems for a given extract and by checking the last update time on the heartbeat at the target you could also determine if data has stopped flowing between the source and target.  Click here to view the document

• RPG Monster-Area, Spawn, Loot table Design

  - by daemonfire300

  I currently struggle with creating the database structure for my RPG. I got so far: tables: area (id) monster (id, area.id, monster.id, hp, attack, defense, name) item (id, some other values) loot (id = monster.id, item = item.id, chance) spawn (id = area.id, monster = monster.id, count) It is a browser-based game like e.g. Castle Age. The player can move from area to area. If a player enters an area the system spawns, based on the area.id and using the spawn table data, new monsters into the monster table. If a player kills a monster, the system picks the monster.id looks up the items via the the loot table and adds those items to the player's inventory. First, is this smart? Second, I need some kind of "monster_instance"-table and "area_instance"-table, since each player enters his very own "area" and does damage to his very own "monsters". Another approach would be adding the / a player.id to the monster table, so each monster spawned, has it's own "player", but I still need to assign them to an area, and I think this would overload the monster table if I put in the player.id and the area.id into the monster table. What are your thoughts? Temporary Solution monster (id, attackDamage, defense, hp, exp, etc.) monster_instance (id, player.id, area_instance.id, hp, attackDamage, defense, monster.id, etc.) area (id, name, area.id access, restriction) area_instance (id, area.id, last_visited) spawn (id, area.id, monster.id) loot (id, monster.id, chance, amount, ?area.id?) An example system-flow would be: Player enters area 1: system creates area_instance of type area.id = 1 and sets player.location to area.id = 1 If Player wants to battle monsters in the current area: system fetches all spawn entries matching area.id == player.location and creates a new monster_instance for each spawn by fetching the according monster-base data from table monster. If a monster is fetched more than once it may be cached. If Player actually attacks a monster: system updates the according monster_instance, if monster dies the instance if removed after creating the loot If Player leaves the area: area_instance.last_visited is set to NOW(), if player doesn't return to data area within a certain amount of time area_instance including all its monster_instances are deleted.

• Building an MVC application using QuickBooks

  - by dataintegration

  RSSBus ADO.NET Providers can be used from many tools and IDEs. In this article we show how to connect to QuickBooks from an MVC3 project using the RSSBus ADO.NET Provider for QuickBooks. Although this example uses the QuickBooks Data Provider, the same process can be used with any of our ADO.NET Providers. Creating the Model Step 1: Download and install the QuickBooks Data Provider from RSSBus. Step 2: Create a new MVC3 project in Visual Studio. Add a data model to the Models folder using the ADO.NET Entity Data Model wizard. Step 3: Create a new RSSBus QuickBooks Data Source by clicking "New Connection", specify the connection string options, and click Next. Step 4: Select all the tables and views you need, and click Finish to create the data model. Step 5: Right click on the entity diagram and select 'Add Code Generation Item'. Choose the 'ADO.NET DbContext Generator'. Creating the Controller and the Views Step 6: Add a new controller to the Controllers folder. Give it a meaningful name, such as ReceivePaymentsController. Also, make sure the template selected is 'Controller with empty read/write actions'. Before adding new methods to the Controller, create views for your model. We will add the List, Create, and Delete views. Step 7: Right click on the Views folder and go to Add -> View. Here create a new view for each: List, Create, and Delete templates. Make sure to also associate your Model with the new views. Step 10: Now that the views are ready, go back and edit the RecievePayment controller. Update your code to handle the Index, Create, and Delete methods. Sample Project We are including a sample project that shows how to use the QuickBooks Data Provider in an MVC3 application. You may download the C# project here or download the VB.NET project here. You will also need to install the QuickBooks ADO.NET Data Provider to run the demo. You can download a free trial here. To use this demo, you will also need to modify the connection string in the 'web.config'.

• Pay in the future should make you think in the present

  - by BuckWoody

  Distributed Computing - and more importantly “-as-a-Service” models of computing have a different cost model. This is something that sounds obvious on the surface but it’s often forgotten during the design and coding phase of a project. In on-premises computing, we’re used to purchasing a server and all of the hardware infrastructure and software licenses needed not only for one project, but several. This is an up-front or “sunk” cost that we consume by running code the organization needs to perform its function. Using a direct connection over wires you’ve already paid for, we don’t often have to think about bandwidth, hits on the data store or the amount of compute we use - we just know more is better. In a pay-as-you-go model, however, each of these architecture decisions has a potential cost impact. The amount of data you store, the number of times you access it, and the amount you send back all come with a charge. The offset is that you don’t buy anything at all up-front, so that sunk cost is freed up. And financial professionals know that money now is worth more than money later. Saving that up-front cost allows you to invest it in other things. It’s not just that you’re using things that now cost money - it’s that the design itself in distributed computing has a cost impact. That can be a really good thing, such as when you dynamically add capacity for paying customers. If you can tie back the cost of a series of clicks to what a user will pay to do so, you can set a profit margin that is easy to track. Here’s a case in point: Assume you are using a large instance in Windows Azure to compute some data that you retrieve from a SQL Azure database. If you don’t monitor the path of the application, you may not know what you are really using. Since you’re paying by the size of the instance, it’s best to maximize it all the time. Recently I evaluated just this situation, and found that downsizing the instance and adding another one where needed, adding a caching function to the application, moving part of the data into Windows Azure tables not only increased the speed of the application, but reduced the cost and more closely tied the cost to the profit. The key is this: from the very outset - the design - make sure you include metrics to measure for the cost/performance (sometimes these are the same) for your application. Windows Azure opens up awesome new ways of doing things, so make sure you study distributed systems architecture before you try and force in the application design you have on premises into your new application structure.

• How to leverage the internal HTTP endpoint available on Azure web roles?

  - by Alfredo Delsors

  Imagine you have a Web application using an in-memory collection that changes occasionally but is used very often. The collection gets loaded from storage on the Application_Start global.asax event and is updated whenever its content changes. If you want to deploy this application on Azure you need to keep in mind that more than one instance of the application can be running at any time and therefore you need to provide some mechanism to keep all instances informed with the latest changes. Because the communication through internal endpoints between Azure role instances is at no cost, a good solution can be maintaining the information on Azure Storage Tables, reading its contents on the Application_Start event and populating its changes to all other instances using the internal HTTP port available on Azure Web Roles. You need to follow these steps to leverage the internal HTTP endpoint available on Azure web roles to maintain all instances up to date. 1.   Define an internal HTTP endpoint in the Web Role properties, for example InternalHttpEndpoint   2.   Add a new WCF service to the Web Role, for example NotificationService.svc 3.   Disable multiple site bindings in web.config: <serviceHostingEnvironment multipleSiteBindingsEnabled="false"> 4.   Add a method on the new service to receive notifications from other role instances. namespace Service { [ServiceContract] public interface INotificationService { [OperationContract(IsOneWay = true)] void Notify(Information info); } } 5.   Declare a class that inherits from System.ServiceModel.Activation.ServiceHostFactory and override the method CreateServiceHost to host the internal endpoint. public class InternalServiceFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { var internalEndpointAddress = string.Format( "http://{0}/NotificationService.svc", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["InternalHttpEndpoint"].IPEndpoint); ServiceHost host = new ServiceHost( typeof(NotificationService), new Uri(internalEndpointAddress)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); host.AddServiceEndpoint( typeof(INotificationService), binding, internalEndpointAddress); return host; } } Note that you can use SecurityMode.None because the internal endpoint is private to the instances of the service. 6.   Edit the markup of the service right clicking the svc file and selecting "View markup" to add the new factory as the factory to be used to create the service <%@ ServiceHost Language="C#" Debug="true" Factory="Service.InternalServiceFactory" Service="Service.NotificationService" CodeBehind="NotificationService.svc.cs" %> 7.   Now you can notify changes to other instances using this code: var current = RoleEnvironment.CurrentRoleInstance; var endPoints = current.Role.Instances .Where(instance => instance != current) .Select(instance => instance.InstanceEndpoints["InternalHttpEndpoint"]); foreach (var ep in endPoints) { EndpointAddress address = new EndpointAddress( String.Format("http://{0}/NotificationService.svc", ep.IPEndpoint)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); var factory = new ChannelFactory<INotificationService>(binding); INotificationService instance = factory.CreateChannel(address); instance.Notify(changedinfo); }

• Using HBase or Cassandra for a token server

  - by crippy

  I've been trying to figure out how to use HBase/Cassandra for a token system we're re-implementing. I can probably squeeze quite a lot more from MySQL, but it just seems it has come to clinging on to the wrong tool for the task just because we know it well. Eventually will hit a wall (like happened to us in other areas). Naturally I started looking into possible NoSQL solutions. The prominent ones (at least in terms of buzz) are HBase and Cassandra. The story is more or less like this: A user can send a gift other users. Each gift has a list of recipients or is public in which case limited by number or expiration date For each gift sent we generate some token that uniquely identifies that gift. For each gift we track the list of potential recipients and their current status relating to that gift (accepted, declinded etc). A user can request to see all his currently pending gifts A can request a list of users he has sent a gift to today (used to limit number of gifts sent) Required the ability to "dump" or "ignore" expired gifts (x day old gifts are considered expired) There are some other requirements but I believe the above covers the essentials. How would I go and model that using HBase or Cassandra? Well, the wall was performance. A few 10s of millions of records per day over 2 tables kept for 2 weeks (wish I could have kept it for more but there was no way). The response times kept getting slower and slower until eventually we had to start cutting down number of days we kept data. Caching helps here but it's not an ideal solution since a big part of the ops are updates. Also, as I hinted in my original post. We use MySQL extensively. We know exactly what it can and can't do both in naive implementations followed by native partitioning and finally by horizontally sharding our dataset on the application level to reside on multiple DB nodes. It can be done, but that's not really what I'm trying to get from this. I asked a very specific question about designing a solution using a NoSQL solution since it's very hard to find examples for designs out there. Brainlag, not trying to come off as rude. I actually appreciate it a lot that you are the only one who even bothered to respond. but I see it over and over again. People ask questions and others assume they have no idea what they're talking about and give an irrelevant answer. Ignore RDBMS please. The question is about nosql.

• Design pattern to handle queries using multiple models

  - by coderkane

  I am presented with a dilemma while trying to re-designing the class structure for my PHP/MySQL application to make it more elegant and conform it to the SOLID principle. The problem goes like this: Let as assume, there is an abstract class called person which has certain properties to define a generic person, such as name, age, date of birth etc. There are two classes, student, and teacher, that implements this abstract class. They add their own unique properties to it. I have designed all the three classes to include all the operational logic (details of which are not relevant in context of the question). Now, I need to create views/reports/data grids which contain details from multiple classes, for example, say, a list of all students doing projects in Chemistry mentored by a teacher whose name is the parameter to the query. This is just one example of a view, there are many different views in the application, which uses data from 3-4 tables, and each of them have multiple input parameters to generate them. Considering this particular example, I have written the relevant query using JOIN and the results are as expected and proper, now here is the dilemma: Keeping in mind the single responsibility principle, where should I keep this query? It does not belong to either Student class, or Teacher class or any other classes currently present. a) Should I create a new class, say dataView class, and design it as a MVC pattern and keep the query there? What about the other views? how do they fit in this architecture? b) Should I not keep the query in code at all, and make it DB View ? c) Am I completely wrong in the approach? If so what is the right approach? My considerations are as follows: a) should be easy to add new views later on if requirement comes, without having to copy-paste-modify code b) would like to make it as loosely coupled as possible so that if minor db structure changes happen, it does not break I did google searches on report design and OOP report generators, but all the result seem to focus on the visual design of the report rather than fetching the data. I have already taken care of the visual aspect of the report using MVC with html templates. I am sure this is a very fundamental problem with known solution, but I am somehow not able to find it (maybe searching with wrong keyword). Edit1: Modified the title to make it more relevant Edit2: The accepted answer got me thinking in the right direction and identify my design flaws, which eventually led me to find this question and the solution in Stack Overflow which gave me the detailed answer to clear the confusion.

• Agile Documentation

  - by Nick Harrison

  We all know that one of the premises of the agile manifesto is to value Working Software over Comprehensive Documentation. This is a wonderful idea and it takes a tremendous burden off of project implementations. I have seen as many projects fail because of the maintenance weight of the project documentations as I have for any reason. But this goal as important as it is may not always be practical. Sometimes the client will simply insist on tedious documentation despite the arguments against it. This may be to calm a nervous client. This may be to satisfy an audit / compliance requirement. This may be a non-too subtle attempt at sabotaging the project. Ok, it is probably not an all out attempt to sabotage the project, but it will probably feel that way. So what can we do to keep to the spirit of the Agile Manifesto but still meet the needs of the client wanting the documentation? This is a good question that I have been puzzling over lately! I hope to explore some possible answers more fully here. A common theme that my solutions are likely to follow is the same theme that I often follow with simplifying complex business logic. Make it table driven! My thought is that the sought after documentation could be a report or reports out of a metadata repository. Reports are much easier to maintain than hand written documentation. Here are a few additional advantages that we can explore over time: Reports will take advantage of the fact that different people have different needs and different format requirements Reports and the supporting metadata are more easily validated and the validation can be automated. If the application itself uses this metadata than there never has to be a question as to whether or not the metadata is up to date. It is up to date or the application would not work. In many cases we should be able to automatically gather most of the Meta data that we need using reflection, system tables, etc. I think that this will lower the total cost of ownership for the documentation and may provide something useful beyond having a pretty document to look at.  What are your thoughts?

• Microsoft BUILD 2013&ndash;Day 1 Summary

  - by Tim Murphy

  Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/27/microsoft-build-2013ndashday-1-summary.aspx I’m happy to be at BUILD this week, mainly because my flights finally got me here late on Tuesday.  My biggest complaints so far are the flights and the hotel.  It seems that almost every flight into San Francisco were delayed multiple hours.  The Sequester so lovingly forced on America by congress means that the airport was short controllers.   That, along with poor weather and airport construction meant most people were 2-3 hours late arriving.  Add on top of that the fact that the hotel that I picked durring registration is absolutely horrid.  It looks like something out of a ghost hunters show and smells like it too.  I think if Microsoft is going to select a hotel they need to make sure that it is adequate. Rant over! So what happened the first day?  Steve Balmer started off the keynote along with Julie Larson-Green and a cast of others.  We finally found out that there were around six thousand people attending BUILD and that the focus this year would be Windows 8, Windows Phone 8 and Azure.  For the rest of the keynote I am going to have a separate post. You can’t have a Microsoft conference without some fun.  This year they have a hunt for pins that represent different gestures in Windows 8.  I got all of mine.  Now they just need to pull my name. The sessions I attended were really good. They covered live tiles, what’s new in XAML and building Windows Phone UIs presented by Kraig Brockschmidt, Tim Heuer and Shawn Oster respectively.  These will also be covered in separate posts. The exhibit area was interesting, but somewhat disappointing.  TechEd 2012 I think was better organized and better staffed by the vendors.  It also seemed that the Microsoft teams’ booths were also in need of some organization and staffing. Overall it was a really fun day capped off by all six thousand attendees standing in like to get their Acer 8” tables and Surface Pros.  What a day!  Stay tuned for follow up posts. del.icio.us Tags: BUILD 2013,Windows 8.1,Winodws Phone,XAML,Keynote

• Using BizTalk to bridge SQL Job and Human Intervention (Requesting Permission)

  - by Kevin Shyr

  I start off the process with either a BizTalk Scheduler (http://biztalkscheduledtask.codeplex.com/releases/view/50363) or a manual file drop of the XML message.  The manual file drop is to allow the SQL  Job to call a "File Copy" SSIS step to copy the trigger file for the next process and allows SQL  Job to be linked back into BizTalk processing. The Process Trigger XML looks like the following.  It is basically the configuration hub of the business process <ns0:MsgSchedulerTriggerSQLJobReceive xmlns:ns0="urn:com:something something">   <ns0:IsProcessAsync>YES</ns0:IsProcessAsync>   <ns0:IsPermissionRequired>YES</ns0:IsPermissionRequired>   <ns0:BusinessProcessName>Data Push</ns0:BusinessProcessName>   <ns0:EmailFrom>[email protected]</ns0:EmailFrom>   <ns0:EmailRecipientToList>[email protected]</ns0:EmailRecipientToList>   <ns0:EmailRecipientCCList>[email protected]</ns0:EmailRecipientCCList>   <ns0:EmailMessageBodyForPermissionRequest>This message was sent to request permission to start the Data Push process.  The SQL Job to be run is WeeklyProcessing_DataPush</ns0:EmailMessageBodyForPermissionRequest>   <ns0:SQLJobName>WeeklyProcessing_DataPush</ns0:SQLJobName>   <ns0:SQLJobStepName>Push_To_Production</ns0:SQLJobStepName>   <ns0:SQLJobMinToWait>1</ns0:SQLJobMinToWait>   <ns0:PermissionRequestTriggerPath>\\server\ETL-BizTalk\Automation\TriggerCreatedByBizTalk\</ns0:PermissionRequestTriggerPath>   <ns0:PermissionRequestApprovedPath>\\server\ETL-BizTalk\Automation\Approved\</ns0:PermissionRequestApprovedPath>   <ns0:PermissionRequestNotApprovedPath>\\server\ETL-BizTalk\Automation\NotApproved\</ns0:PermissionRequestNotApprovedPath> </ns0:MsgSchedulerTriggerSQLJobReceive>   Every node of this schema was promoted to a distinguished field so that the values can be used for decision making in the orchestration.  The first decision made is on the "IsPermissionRequired" field.     If permission is required (IsPermissionRequired=="YES"), BizTalk will use the configuration info in the XML trigger to format the email message.  Here is the snippet of how the email message is constructed. SQLJobEmailMessage.EmailBody     = new Eai.OrchestrationHelpers.XlangCustomFormatters.RawString(         MsgSchedulerTriggerSQLJobReceive.EmailMessageBodyForPermissionRequest +         "<br><br>" +         "By moving the file, you are either giving permission to the process, or disapprove of the process." +         "<br>" +         "This is the file to move: \"" + PermissionTriggerToBeGenereatedHere +         "\"<br>" +         "(You may find it easier to open the destination folder first, then navigate to the sibling folder to get to this file)" +         "<br><br>" +         "To approve, move(NOT copy) the file here: " + MsgSchedulerTriggerSQLJobReceive.PermissionRequestApprovedPath +         "<br><br>" +         "To disapprove, move(NOT copy) the file here: " + MsgSchedulerTriggerSQLJobReceive.PermissionRequestNotApprovedPath +         "<br><br>" +         "The file will be IMMEDIATELY picked up by the automated process.  This is normal.  You should receive a message soon that the file is processed." +         "<br>" +         "Thank you!"     ); SQLJobSendNotification(Microsoft.XLANGs.BaseTypes.Address) = "mailto:" + MsgSchedulerTriggerSQLJobReceive.EmailRecipientToList; SQLJobEmailMessage.EmailBody(Microsoft.XLANGs.BaseTypes.ContentType) = "text/html"; SQLJobEmailMessage(SMTP.Subject) = "Requesting Permission to Start the " + MsgSchedulerTriggerSQLJobReceive.BusinessProcessName; SQLJobEmailMessage(SMTP.From) = MsgSchedulerTriggerSQLJobReceive.EmailFrom; SQLJobEmailMessage(SMTP.CC) = MsgSchedulerTriggerSQLJobReceive.EmailRecipientCCList; SQLJobEmailMessage(SMTP.EmailBodyFileCharset) = "UTF-8"; SQLJobEmailMessage(SMTP.SMTPHost) = "localhost"; SQLJobEmailMessage(SMTP.MessagePartsAttachments) = 2;   After the Permission request email is sent, the next step is to generate the actual Permission Trigger file.  A correlation set is used here on SQLJobName and a newly generated GUID field. <?xml version="1.0" encoding="utf-8"?><ns0:SQLJobAuthorizationTrigger xmlns:ns0="somethingsomething"><SQLJobName>Data Push</SQLJobName><CorrelationGuid>9f7c6b46-0e62-46a7-b3a0-b5327ab03753</CorrelationGuid></ns0:SQLJobAuthorizationTrigger> The end user (the human intervention piece) will either grant permission for this process, or deny it, by moving the Permission Trigger file to either the "Approved" folder or the "NotApproved" folder.  A parallel Listen shape is waiting for either response.   The next set of steps decide how the SQL Job is to be called, or whether it is called at all.  If permission denied, it simply sends out a notification.  If permission is granted, then the flag (IsProcessAsync) in the original Process Trigger is used.  The synchonous part is not really synchronous, but a loop timer to check the status within the calling stored procedure (for more information, check out my previous post:  http://geekswithblogs.net/LifeLongTechie/archive/2010/11/01/execute-sql-job-synchronously-for-biztalk-via-a-stored-procedure.aspx)  If it's async, then the sp starts the job and BizTalk sends out an email.   And of course, some error notification:   Footnote: The next version of this orchestration will have an additional parallel line near the Listen shape with a Delay built in and a Loop to send out a daily reminder if no response has been received from the end user.  The synchronous part is used to gather results and execute a data clean up process so that the SQL Job can be re-tried.  There are manu possibilities here.

• How do you handle objects that need custom behavior, and need to exist as an entity in the database?

  - by Scott Whitlock

  For a simple example, assume your application sends out notifications to users when various events happen. So in the database I might have the following tables: TABLE Event EventId uniqueidentifier EventName varchar TABLE User UserId uniqueidentifier Name varchar TABLE EventSubscription EventUserId EventId UserId The events themselves are generated by the program. So there are hard-coded points in the application where an event instance is generated, and it needs to notify all the subscribed users. So, the application itself doesn't edit the Event table, except during initial installation, and during an update where a new Event might be created. At some point, when an event is generated, the application needs to lookup the Event and get a list of Users. What's the best way to link the event in the source code to the event in the database? Option 1: Store the EventName in the program as a fixed constant, and look it up by name. Option 2: Store the EventId in the program as a static Guid, and look it up by ID. Extra Credit In other similar circumstances I may want to include custom behavior with the event type. That is, I'll want subclasses of my Event entity class with different behaviors, and when I lookup an event, I want it to return an instance of my subclass. For instance: class Event { public Guid Id { get; } public Guid EventName { get; } public ReadOnlyCollection<EventSubscription> EventSubscriptions { get; } public void NotifySubscribers() { foreach(var eventSubscription in EventSubscriptions) { eventSubscription.Notify(); } this.OnSubscribersNotified(); } public virtual void OnSubscribersNotified() {} } class WakingEvent : Event { private readonly IWaker waker; public WakingEvent(IWaker waker) { if(waker == null) throw new ArgumentNullException("waker"); this.waker = waker; } public override void OnSubscribersNotified() { this.waker.Wake(); base.OnSubscribersNotified(); } } So, that means I need to map WakingEvent to whatever key I'm using to look it up in the database. Let's say that's the EventId. Where do I store this relationship? Does it go in the event repository class? Should the WakingEvent know declare its own ID in a static member or method? ...and then, is this all backwards? If all events have a subclass, then instead of retrieving events by ID, should I be asking my repository for the WakingEvent like this: public T GetEvent<T>() where T : Event { ... // what goes here? ... } I can't be the first one to tackle this. What's the best practice?

• .Net Application & Database Modularity/Reuse

  - by Martaver

  I'm looking for some guidance on how to architect an app with regards to modularity, separation of concerns and re-usability. I'm working on an application (ASP.Net, C#) that has distinctly generic chunks of functionality, that I'd love to be able to lift out, all layers, into re-usable components. This means the module handles the database schema, data access, API, everything so that the next time I want to use it I can just register the module and hook into it. Developing modules of re-usable functionality is a no-brainer, but what is really confusing me is what to do when it comes to handling a core re-usable database schema that serves the module's functionality. In an ideal world, I would register a module and it would ensure that the associated database schema exists in the DB. I would code on the assumption that the tables exist, calling the module's functionality through the DLL, agnostic of the database layer. Kind of like Enterprise Library's Caching/Logging Application Block, which can create a DB schema in the target DB to use as a data store. My Questions is: What do you think is the best way to achieve this, firstly, in terms design architecture, and secondly solution structure. What patterns/frameworks do you know that exist & support this kind of thing? My thoughts so far: I mostly use Entity Framework and SQL Server DB Projects. I thought about a 'black box' approach to modules of functionality. I could use use a code-first approach in EF4, and use the ObjectContext to create a database when the module is initialized. However this means that all of the entities that my module encapsulates would be disconnected from the rest of the application because they belonged to an abstracted ObjectContext. Further - Creating appropriate indexes and references between domain entities and the module's entities would be impossible to do practically. I've thought of adopting Enterprise Library and creating my own Application Blocks. I'm not sure how this would play nice with Entity Framework (if at all) though. I like the idea of building on proven patterns & practices to encapsulate established, reusable functionality. I thought of abandoning Entity Framework for the Module, and just creating a separate DB schema for the module with its own set of stored procedures & ADO.Net. Then deploying the script at run-time if interrogation shows that it doesn't exist. But once again, for application developing outside of the application, I would want to use Entity Framework and I would have to use the module separately, disconnected from the domain ObjectContext. Has anyone had experience developing these sorts of full-stack modules? What advice can you offer? Am I biting off more than I can chew?

• WebCenter Content Web Search Performance: Do you really need that folder path info?

  - by Nicolas Montoya

  End-users want content at their fingertips at the speed of thought if possible. When running search operations in the WebCenter Conter Web Interface every second or fraction of a second improvement does matter. When doing some trace analysis on the systemdatabase tracing on a customer environment, we came across some SQL queries that were unnecessarily being triggered! These were related to determining the folder path for every entry part of the search result set. However, this folder path was not even being used as part of the displayed information in the user interface.Why was the folder path information being collected when it was not even displayed in the UI? We found that the configuration parameter 'FolderPathInSearchResults' was set to 'true' under Administration > Admin Server > General Configuration > Additional Configuration Variables as shown below:When executing a quicksearch by keyword we were getting 100 out of 2280 entries in the first page of the result set.When thera 'FolderPathInSearchResults' configuration parameter is set to 'true', the following queries appear in the systemdatabase tracing:100 executions for a query on the FolderFiles table for each of the documents displayed in the first page:>systemdatabase/6       12.13 11:17:48.188      IdcServer-199   1.45 ms. SELECT * FROM FolderFiles WHERE dDocName='SLC02VGVUSORAC140641' AND fLinkRank=0[Executed. Returned row(s): true]382 executions for a query of the folders tables - most of the documents that match the keyword criteria are at a folder depth level of three or four:>systemdatabase/6       12.13 11:17:48.114      IdcServer-199   2.57 ms. SELECT FolderFolders.*,FolderMetaDefaults.* FROM FolderFolders,FolderMetaDefaults WHERE FolderFolders.fFolderGUID=FolderMetaDefaults.fFolderGUID(+) AND((FolderFolders.fFolderGUID = '1EB8E527E19B09ED3FE82EE310AEA13A' ) )[Executed.Returned row(s): true]By setting this 'FolderPathInSearchResults' configuration parameter to 'false', the above queries were no longer reported in the Server Output System Audit Information.Now, let's consider a practical scenario:Search result set page = 100Average folder depth der document in the search result set: 5The number of folder path related queries will be: 100 + 5*500 = 600If each query takes slightly over 3 ms. You would have 2000 ms (2 seconds) spent in server time to get this information.The overall performance impact goes beyond seerver time execution, as this information needs to travel from the server to the browser. If the documents are further nested into the folder hierarchy, additional hundreds of queries may be executed. If folder path is not being displayed in the end-user interface profile, your system may be better of with the 'FolderPathInSearchResults' configuration parameter disabled.
