  • Minimizing data sent over a webservice call on expensive connection

    - by aceinthehole
    I am working on a system that has many remote laptops all connected to the internet through cellular data connections. The application will synchronize periodically to a central database. The problem is, due to factors outside our control, the cost to move data across the cellular networks are spectacularly expensive. Currently the we are sending a compressed XML file across the wire where it is being processed and various things are done with (mainly stuffing it into a database). My first couple of thoughts were to convert that XML doc to json, just prior to transmission and convert back to XML just after receipt on the other end, and get some extra compression for free without changing much. Another thought was to test various other compression algorithms to determine the smallest one possible. Although, I am not entirely sure how much difference json vs xml would make once it is compressed. I thought that their must be resources available that address this problem from an information theory perspective. Does anyone know of any such resources or suggestions on what direction to go in. This developed on the MS .net stack on windows for reference.

  • Sorting a Grid of Data in ASP.NET MVC

    Last week's article, Displaying a Grid of Data in ASP.NET MVC, showed, step-by-step, how to display a grid of data in an ASP.NET MVC application. Last week's article started with creating a new ASP.NET MVC application in Visual Studio, then added the Northwind database to the project and showed how to use Microsoft's Linq-to-SQL tool to access data from the database. The article then looked at creating a Controller and View for displaying a list of product information (the Model). This article builds on the demo application created in Displaying a Grid of Data in ASP.NET MVC, enhancing the grid to include bi-directional sorting. If you come from an ASP.NET WebForms background, you know that the GridView control makes implementing sorting as easy as ticking a checkbox. Unfortunately, implementing sorting in ASP.NET MVC involves a bit more work than simply checking a checkbox, but the quantity of work isn't significantly greater and with ASP.NET MVC we have more control over the grid and sorting interface's layout and markup, as well as the mechanism through which sorting is implemented. With the GridView control, sorting is handled through form postbacks with the sorting parameters - what column to sort by and whether to sort in ascending or descending order - being submitted as hidden form fields. In this article we'll use querystring parameters to indicate the sorting parameters, which means a particular sort order can be indexed by search engines, bookmarked, emailed to a colleague, and so on - things that are not possible with the GridView's built-in sorting capabilities. Like with its predecessor, this article offers step-by-step instructions and includes a complete, working demo available for download at the end of the article. Read on to learn more! Read More >

  • sp_ssiscatalog v1.0.1.0 now available for download

    - by jamiet
    13 days ago I wrote a blog post entitled Introducing sp_ssiscatalog (v1.0.0.0) in which I first made mention of sp_ssiscatalog, an open source stored procedure intended to make it easy to query the SSIS Catalog. I have been working on some enhancements since then and hence v1.0.1.0 is now available for download from Codeplex. What’s new in this release This release includes the following enhancements: [execution_id] now gets returned in a call to EXEC [dbo].[sp_ssiscatalog] @operation_type='exec'; Filter events by specifying packages to ignore EXEC [dbo].[sp_ssiscatalog] @operation_type='exec',@exec_events_packagesexcluded='SomePackage.dtsx,AnotherPackage.dtsx'; [event_message_id] is now returned in a list of events List of executions can now be filtered via a minimum and maximum execution_id EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_minimum_execution_id=198,@execs_maximum_execution_id=201 Events resultsets now have a field, [event_message_context_xml] that contains an XML document containing all [event_message_context] info (if any exists) Installation instructions Download the zip file at DB v1.0.1.0. It contains two files, SsisReportingPack.dacpac & SSISDB.dacpac Unzip to a folder of your choosing Open a command prompt and change to the directory into which you unzipped the files Execute: "%PROGRAMFILES(x86)%\Microsoft SQL Server\110\DAC\bin\sqlpackage.exe" /a:Publish /tdn:SsisReportingPack /sf:SSISReportingPack.dacpac /v:SSISDB=SSISDB /tsn:(local) (/tsn specifies the target server. Change as appropriate.) If everything works OK you’ll see something like the following: or depending on whether the target database already exists or not This will create a database called [SsisReportingPack] which contains [dbo].[sp_ssiscatalog] Feedback is welcomed! @Jamiet

  • Save password in WCF adapter binding file

    - by Edmund Zhao
    Binding file for WCF Adapter doesn't save the password no matter it is generated by "Add Generated Items..." wizard in Visual Studio or "Export Bindings..." in administration console. It is by design dut to the consideration of security, but it is very annoying especially when you import bindings which contain multiple WCF send ports. The way to aviod retyping password everytime after an import is to edit the binding file before import. Here is what needs to be done. 1. Find the following string:     &lt;Password vt="1" /&gt; "&lt;" means "<", "&gt;" means ">", "vt" means "Variable Type", variable type 1 is "NULL", so the above string can be translated to "<Password/>" 2. Replace it with:     &lt;Password vt="8"&gt;MyPassword&lt;/Password&gt;    variable type 8 is "string", the above string can be transalted to "<Password>MyPassword</Password>"   Binding file uses a lot of character entity references for XML character encoding purpose. For a list of the special charactor entiy references, you can check from here. ...Edmund Zhao

  • Class hierarchy problem in this social network model

    - by Gerenuk
    I'm trying to design a class system for a social network data model - basically a link/object system. Now I have roughly the following structure (simplified and only relevant methods shown) class Data: "used to handle the data with mongodb" "can link, unlink data and also return other linked data" "is basically a proxy object that only stores _id and accesses mongodb on requests" "it looks like {_id: ..., _out: [id1, id2,...], _inc: [id3, id4, ...]}" def get_node(self, id) "create a new Data object from the underlying mongodb" "each data object can potentially create a reference object to new mongo data" "this is needed when the data returns the linked objects" class Node: """ this class proxies linking calls to .data it includes additional network logic operations whereas Data only contains a basic database solution """ def __init__(self, data): "the infrastructure realization is stored as composition by an included object data" "Node bascially proxies most calls to the infrastructure object data" def get_node(self, data): "creates a new object of class Object or Link depending on data" class Object(Node): "can have multiple connections to Link" class Link(Node): "has one 'in' and one 'out' connection to an Object" This system is working, however maybe wouldn't work outside Python. Note that after reading links Now I have two questions here: 1) I want to infrastructure of the data storage to be replacable. Earlier I had Data as a superclass of Node so that it provided the neccessary calls. But (without dirty Python tricks) you cannot replace the superclass dynamically. Is using composition therefore recommended? The drawback is that I have to proxy most calls (link, unlink etc). Any thoughts? 2) The class Node contains the common method .get_node which is used to built new Object or Link instances after reading out the data. Some attribute of data decided whether the object which is only stored by id should be instantiated as an Object or Link class. The problem here is that Node needs to know about Object and Link in advance, which seems dodgy. Do you see a different solution? Both Object and Link need to instantiate one of all possible types depending on what the find in their linked data. Are there any other ideas how to implement a flexible Object/Link structure where the underlying database storage is isolated?

  • Data that has been deleted in P6, how is it updated in Analytics

    - by Jeffrey McDaniel
    In P6 Reporting Database 2.0 the ETL process looked to the refrdel table in the P6 PMDB to determine which projects were deleted. The refrdel table could not be cleared out between ETL runs or those deletes would be lost. After the ETL process is run the refrdel can be cleared out. It is important to keep any purging of the refrdel in a consistent cycle so the ETL process can pick up these deletes and process them accordingly.  In P6 Reporting Database 2.2 and higher the Extended Schema is used as the data source. In the Extended Schema, deleted data is filtered out by the views. The Extended Schema services will handle any interaction with the refrdel table, this concern with timing refrdel cleanup and ETL runs is not applicable as of this release. In the Extended Schema tables (ex. TaskX) there can still be deleted data present. The Extended Schema views join on the primary PMDB tables (ex. Task) and filter out any deleted data.  Any data that was deleted that remains in the Extended Schema tables can be cleaned out at a designated time by running the clean up procedure as documented in the P6 Extended Schema white paper. This can be run occasionally but is not necessary to run often unless large amounts of data has been deleted.

  • TCO Comparison: Oracle Exadata vs IBM P-Series

    - by Javier Puerta
    Cost Comparison for Business Decision-makersOracle Exadata Database Machine vs. IBM Power SystemsHow to Weigh a Purchase DecisionOctober 2012 Download full report here In this research-based  white paper conducted at the request of Oracle, The FactPoint Group compares the cost of ownership of the Oracle Exadata engineered system to a traditional build-your-own (BYO) solution, in this case an IBM Power 770 (P770) with SAN storage.  The IBM P770 was chosen given it is IBM’s current most popular model, based on FactPoint primary and secondary research and IBM claims, and because at least one of the interviewed customers had specifically migrated from a P770 to Exadata, affording us a more specific data point for comparison. This research found that Oracle Exadata: Can be deployed more quickly and easily requiring 59% fewer man-hours than a traditional IBM Power Systems solution. Delivers dramatically higher performance typically up to 12X improvement, as described by customers, over their prior solution.  Requires 40% fewer systems administrator hours to maintain and operate annually, including quicker support calls because of less finger-pointing and faster service with a single vendor.  Will become even easier to operate over time as users become more proficient and organize around the benefits of integrated infrastructure. Supplies a highly available, highly scalable and robust solution that results in reserve capacity that make Exadata easier for IT to operate because IT administrators can manage proactively, not reactively.  Overall, Exadata operations and maintenance keep IT administrators from “living on the edge.”  And it’s pre-engineered for long-term growth. Finally, compared to IBM Power Systems hardware, Exadata is a bargain from a total cost of ownership perspective:  Over three years, the IBM hardware running Oracle Database cost 31% more in TCO than Exadata.

  • Meet the New Windows Azure

    - by ScottGu
    Today we are releasing a major set of improvements to Windows Azure.  Below is a short-summary of just a few of them: New Admin Portal and Command Line Tools Today’s release comes with a new Windows Azure portal that will enable you to manage all features and services offered on Windows Azure in a seamless, integrated way.  It is very fast and fluid, supports filtering and sorting (making it much easier to use for large deployments), works on all browsers, and offers a lot of great new features – including built-in VM, Web site, Storage, and Cloud Service monitoring support. The new portal is built on top of a REST-based management API within Windows Azure – and everything you can do through the portal can also be programmed directly against this Web API. We are also today releasing command-line tools (which like the portal call the REST Management APIs) to make it even easier to script and automate your administration tasks.  We are offering both a Powershell (for Windows) and Bash (for Mac and Linux) set of tools to download.  Like our SDKs, the code for these tools is hosted on GitHub under an Apache 2 license. Virtual Machines Windows Azure now supports the ability to deploy and run durable VMs in the cloud.  You can easily create these VMs using a new Image Gallery built-into the new Windows Azure Portal, or alternatively upload and run your own custom-built VHD images. Virtual Machines are durable (meaning anything you install within them persists across reboots) and you can use any OS with them.  Our built-in image gallery includes both Windows Server images (including the new Windows Server 2012 RC) as well as Linux images (including Ubuntu, CentOS, and SUSE distributions).  Once you create a VM instance you can easily Terminal Server or SSH into it in order to configure and customize the VM however you want (and optionally capture your own image snapshot of it to use when creating new VM instances).  This provides you with the flexibility to run pretty much any workload within Windows Azure.   The new Windows Azure Portal provides a rich set of management features for Virtual Machines – including the ability to monitor and track resource utilization within them.  Our new Virtual Machine support also enables the ability to easily attach multiple data-disks to VMs (which you can then mount and format as drives).  You can optionally enable geo-replication support on these – which will cause Windows Azure to continuously replicate your storage to a secondary data-center at least 400 miles away from your primary data-center as a backup. We use the same VHD format that is supported with Windows virtualization today (and which we’ve released as an open spec), which enables you to easily migrate existing workloads you might already have virtualized into Windows Azure.  We also make it easy to download VHDs from Windows Azure, which also provides the flexibility to easily migrate cloud-based VM workloads to an on-premise environment.  All you need to do is download the VHD file and boot it up locally, no import/export steps required. Web Sites Windows Azure now supports the ability to quickly and easily deploy ASP.NET, Node.js and PHP web-sites to a highly scalable cloud environment that allows you to start small (and for free) and then scale up as your traffic grows.  You can create a new web site in Azure and have it ready to deploy to in under 10 seconds: The new Windows Azure Portal provides built-in administration support for Web sites – including the ability to monitor and track resource utilization in real-time: You can deploy to web-sites in seconds using FTP, Git, TFS and Web Deploy.  We are also releasing tooling updates today for both Visual Studio and Web Matrix that enable developers to seamlessly deploy ASP.NET applications to this new offering.  The VS and Web Matrix publishing support includes the ability to deploy SQL databases as part of web site deployment – as well as the ability to incrementally update database schema with a later deployment. You can integrate web application publishing with source control by selecting the “Set up TFS publishing” or “Set up Git publishing” links on a web-site’s dashboard: Doing do will enable integration with our new TFS online service (which enables a full TFS workflow – including elastic build and testing support), or create a Git repository that you can reference as a remote and push deployments to.  Once you push a deployment using TFS or Git, the deployments tab will keep track of the deployments you make, and enable you to select an older (or newer) deployment and quickly redeploy your site to that snapshot of the code.  This provides a very powerful DevOps workflow experience.   Windows Azure now allows you to deploy up to 10 web-sites into a free, shared/multi-tenant hosting environment (where a site you deploy will be one of multiple sites running on a shared set of server resources).  This provides an easy way to get started on projects at no cost. You can then optionally upgrade your sites to run in a “reserved mode” that isolates them so that you are the only customer within a virtual machine: And you can elastically scale the amount of resources your sites use – allowing you to increase your reserved instance capacity as your traffic scales: Windows Azure automatically handles load balancing traffic across VM instances, and you get the same, super fast, deployment options (FTP, Git, TFS and Web Deploy) regardless of how many reserved instances you use. With Windows Azure you pay for compute capacity on a per-hour basis – which allows you to scale up and down your resources to match only what you need. Cloud Services and Distributed Caching Windows Azure also supports the ability to build cloud services that support rich multi-tier architectures, automated application management, and scale to extremely large deployments.  Previously we referred to this capability as “hosted services” – with this week’s release we are now referring to this capability as “cloud services”.  We are also enabling a bunch of new features with them. Distributed Cache One of the really cool new features being enabled with cloud services is a new distributed cache capability that enables you to use and setup a low-latency, in-memory distributed cache within your applications.  This cache is isolated for use just by your applications, and does not have any throttling limits. This cache can dynamically grow and shrink elastically (without you have to redeploy your app or make code changes), and supports the full richness of the AppFabric Cache Server API (including regions, high availability, notifications, local cache and more).  In addition to supporting the AppFabric Cache Server API, it also now supports the Memcached protocol – allowing you to point code written against Memcached at it (no code changes required). The new distributed cache can be setup to run in one of two ways: 1) Using a co-located approach.  In this option you allocate a percentage of memory in your existing web and worker roles to be used by the cache, and then the cache joins the memory into one large distributed cache.  Any data put into the cache by one role instance can be accessed by other role instances in your application – regardless of whether the cached data is stored on it or another role.  The big benefit with the “co-located” option is that it is free (you don’t have to pay anything to enable it) and it allows you to use what might have been otherwise unused memory within your application VMs. 2) Alternatively, you can add “cache worker roles” to your cloud service that are used solely for caching.  These will also be joined into one large distributed cache ring that other roles within your application can access.  You can use these roles to cache 10s or 100s of GBs of data in-memory very effectively – and the cache can be elastically increased or decreased at runtime within your application: New SDKs and Tooling Support We have updated all of the Windows Azure SDKs with today’s release to include new features and capabilities.  Our SDKs are now available for multiple languages, and all of the source in them is published under an Apache 2 license and and maintained in GitHub repositories. The .NET SDK for Azure has in particular seen a bunch of great improvements with today’s release, and now includes tooling support for both VS 2010 and the VS 2012 RC. We are also now shipping Windows, Mac and Linux SDK downloads for languages that are offered on all of these systems – allowing developers to develop Windows Azure applications using any development operating system. Much, Much More The above is just a short list of some of the improvements that are shipping in either preview or final form today – there is a LOT more in today’s release.  These include new Virtual Private Networking capabilities, new Service Bus runtime and tooling support, the public preview of the new Azure Media Services, new Data Centers, significantly upgraded network and storage hardware, SQL Reporting Services, new Identity features, support within 40+ new countries and territories, and much, much more. You can learn more about Windows Azure and sign-up to try it for free at http://windowsazure.com.  You can also watch a live keynote I’m giving at 1pm June 7th (later today) where I’ll walk through all of the new features.  We will be opening up the new features I discussed above for public usage a few hours after the keynote concludes.  We are really excited to see the great applications you build with them. Hope this helps, Scott

  • How to analyze data

    - by Subhash Dike
    We are working on an application that allows user to search/read some content in a particular domain. We wanted to add some capability in the app which can suggest user some content based on the usage pattern (analyze data based on frequency and relevance). Currently every time user search or read something we do store that information in backend database. We would like to use this data to present some additional content to user. Could someone explain what kind of tools will be required for such a job and any example? And what this concept is called, data analysis? data mining? business intelligence? or something else? Update: Sorry for being too broad, here is an example SQL Database (Just to give an idea, actual db is little different with normalization and stuff) Table: UserArticles Fields: UserName | ArticleId | ArticleTitle | DateVisited | ArticleCategory Table: CategoryArticles Fields: Category | Article Title | Author etc. One Category may have one more articles. One user may have read the same article multiple times (in this case we place additional entry in the user article table. Task: Use the information availabel in UserArticle table and rank categories in order which would be presented to user automatically in other part of application. Factors to be considered are frequency and recency. This might be possible through simple queries or may require specialized tools. Either way, the task is what mention above. I am not too sure which route to take, hence the question. Thoughts??

  • OOW content for Pattern Matching....

    - by KLaker
    If you missed my sessions at OpenWorld then don't worry - all the content we used for pattern matching (presentation and hands-on lab) is now available for download. My presentation "SQL: The Best Development Language for Big Data?" is available for download from the OOW Content Catalog, see here: https://oracleus.activeevents.com/2013/connect/sessionDetail.ww?SESSION_ID=9101 For the hands-on lab ("Pattern Matching at the Speed of Thought with Oracle Database 12c") we used the Oracle-By-Example content. The OOW hands-on lab uses Oracle Database 12c Release 1 (12.1) and uses the MATCH_RECOGNIZE clause to perform some basic pattern matching examples in SQL. This lab is broken down into four main steps: Logically partition and order the data that is used in the MATCH_RECOGNIZE clause with its PARTITION BY and ORDER BY clauses. Define patterns of rows to seek using the PATTERN clause of the MATCH_RECOGNIZE clause. These patterns use regular expressions syntax, a powerful and expressive feature, applied to the pattern variables you define. Specify the logical conditions required to map a row to a row pattern variable in the DEFINE clause. Define measures, which are expressions usable in the MEASURES clause of the SQL query. You can download the setup files to build the ticker schema and the student notes from the Oracle Learning Library. The direct link to the example on using pattern matching is here: http://apex.oracle.com/pls/apex/f?p=44785:24:0::NO:24:P24_CONTENT_ID,P24_PREV_PAGE:6781,2.

  • How to motivate visitors to comment

    - by Michal
    At first I must apologize, because I am not sure if this question is valid for webmasters topic. I deal with the problem as being webmaster, however, i think this question is more related with marketing. Nevertheless, I was searching for marketing stack-overflow at meta stack-overflow and did not find such page. Background Four days ago, I launched a portal with database of barber salons at which people can find a salon through various criterions, see its photos, details, and also put a comment with their own opinion. The development took me half a year and it took me other 2 months to fill the database with information about barbers (I've also hired another three people to this job). I have not a big problem with getting people to my portal, I pay for PPC, comment on barber discussions etc.. In past four days I've reached a satisfactory number of visitors. Problem I deal with fact that everyone wants to search and read comments, but no one is willing to put her/his own opinion to barber. So I've tried following (2 days ago): Made comment anonymous, no one has to be afraid of compromise her/his identity with a salon owner I prepared a competition for users in which they can win a cosmetic package if they comment on at least three different salons I payed for PPC campaign on facebook which is telling people about the competition I registered competition on 20 portals for competitions And the result: People are commenting on facebook that the competition is a good idea They are giving likes on facebook But no one put a single comment to a barber salon I am getting little confused about what am I doing wrong. I will be thankful for any advice.

  • Instructor Insight: Dealing with Columns in Oracle JD Edwards Enterprise One Tools Release 9.1

    - by Breanne Cooley
    Oracle JD Edwards Enterprise One Tools Release  9.1 has many new features that will help end users be more efficient in their daily jobs. For example, hiding grid columns is now as easy as a left-mouse click. In earlier releases, users could click on the ‘Customize Grid’ link but still had to do several more clicks to hide or show a column . The following example shows how easy this new feature is to use. First, right-mouse click on the column you want to hide; for example the ‘Long Address’ column. The column is now hidden. Second, right-mouse over on any of the columns to show the ‘Unhide’ option. After you select ‘Unhide’, the hidden column is shown. You can then select the column to show, or unhide, the column. This new feature and others are covered in the JD Edwards EnterpriseOne System Administration Rel 9.x course, which has been updated to reflect the new release. Hope to see you in class! -Randy Richeson, Senior Principal Instructor, Oracle University

  • Desktop application, dependency injection

    - by liori
    I am thinking of applying a real dependency injection library to my toy C#/GTK# desktop application. I chose NInject, but I think this is irrelevant to my question. There is a database object, a main window and several utility window classes. It's clear that I can inject the database into every window object, so here DI is useful. But does it make sense to inject utility window classes into other window classes? Example: I have classes such as: class MainWindow {…} class AddItemWindow {…} class AddAttachmentWindow {…} class BrowseItemsWindow {…} class QueryBuilderWindow {…} class QueryBrowserWindow {…} class PreferencesWindow {…} … Each of the utility classes can be opened from MainWindow. Some utility windows can also be opened from other utility windows. Generally, there might be a really complex graph of who can open whom. So each of those classes might need quite a lot of other window classes injected. I'm worried that such usage will go against the suggestion not to inject too many classes at once and become a code smell. Should I use some kind of a service locator object here?

  • Tools for managing eCommerce backend

    - by rboarman
    I am working with an eCommerce company that has outgrown their hacked together backend for managing inventory, pricing and feeds to various shopping engines (Yahoo, 3d cart, Amazon, etc.). They currently manage about 12,000 skus and are doing $40M in revenue. Their internal people are working on a new Magento solution, but that is six months away and they need to replace/improve their current solution in order to hold them over. Their current solution was developed by two people who have left the company. What tools/architecture do other eCommerce sites use to manage their inventory, pricing, product descriptions and feed generation for the shopping engines? The current solution looks like this: 1) Inventory, pricing and product descriptions are maintained in a database and in NetSuite by employees 2) New products are added to the database via import 3) Twice a week data is extracted into a giant Excel spreadsheet 4) The Excel file adjusts pricing based on some simple algorithms 5) The Excel file exports about six different csv feeds which are manually uploaded to Amazon, 3d cart, Yahoo, Google and Merchant Advantage a. Each feed is a variant of the product which different field names and formatting b. Pricing levels differ between feeds c. Some products are not sent to all feeds 6) Orders are manually parsed and the inventory is adjusted as needed once product is sold The new solution should: 1) Import data from ODBC, CSV and NetSuite (CSV via ftp) 2) Apply pricing changes via simple algorithms (< $80 add $10, $200 add $25) 3) Ensure margins are being met 4) Format and generate a bunch of CSV and XML feeds 5) Perhaps upload feeds to shopping engines automatically What I need to do is replace the Excel file with something that is maintainable and automated. Something in the .Net stack is preferable but not mandatory. I’ve been looking at BizTalk but it may take too long to develop and deploy. Any suggestions?

    I asked this question at stackoverflow and received no response (closed as duplicate with no answer). I'm experimenting with OOP and I have the following basic MVC layout: class Model { // do database stuff } class View { public function load($filename, $data = array()) { if(!empty($data)) { extract($data); } require_once('views/header.php'); require_once("views/$filename"); require_once('views/footer.php'); } } class Controller { public $model; public $view; function __construct() { $this->model = new Model(); $this->view = new View(); // determine what page we're on $page = isset($_GET['view']) ? $_GET['view'] : 'home'; $this->display($page); } public function display($page) { switch($page) { case 'home': $this->view->load('home.php'); break; } } } These classes are brought together in my setup file: // start session session_start(); require_once('Model.php'); require_once('View.php'); require_once('Controller.php'); new Controller(); Now where do I place my database connection code and how do I pass the connection onto the model? try { $db = new PDO('mysql:host='.DB_HOST.';dbname='.DB_DATABASE.'', DB_USERNAME, DB_PASSWORD); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch(PDOException $err) { die($err->getMessage()); } I've read about Dependency Injection, factories and miscellaneous other design patterns talking about keeping SQL out of the model, but it's all over my head using abstract examples. Can someone please just show me a straight-forward practical example?

  • Portal And Content – Introduction (1 of 7)

    - by Stefan Krantz
    The coming post over the next two months will be included in a new series. The idea is to help the reader to understand how to enable a versatile and manageable portal. Each post will go through a specific use case or lifecycle group of events that a Content Driven Portal requires the development team to consider. The current planning is to deliver following subjects, each topic will be enclosed in a separate blog post. Introduction – Introduction to the series of posts and what to expect at the end of the series Components, part 1 – UCM, Site Studio and high level introduction to content templates Components, part 2 – Page Templates and  Navigation model Components, part 3 – Applied Customization Framework for Content Presenter Taskflows Scenario 1 – Enable a Portal for runtime administration Scenario 2 – Enable a Portal for Internationalization Scenario 3 – Enable a Portal for Content Workflows Background This post series has been issued to help customers, partners and consultants to understand the concept of a WebCenter Portal project where the main focus or a majority of the portal has content interaction. Today the most portal installations Oracle WebCenter Portal is involved in have a vast majority of content based pages. Many of the Portal projects have or will run into challenges, to mitigate these challenges the portal and content lifecycle has to be well designed. The coming posts will address the main components that should be involved when creating such scenarios; it will also go into details on the process by describing three solution scenarios. The aim with the scenarios is to give the reader a more hands on understanding of the concept of building and architecting a Content Driven Portal. The selected scenarios are selected based on the most common use cases that we have identified until today.

  • Self Service Reporting With PowerPivot

    - by blakmk
    There are so many cool new features in Sql 2008 release 2 it was difficult for me to pick a topic for T-SQL Tuesday . But the one that I am now a secret fan of, I once resented for its creation. Let me explain, for years I have encountered reporting systems cobbled together in tools like Access and Excel built by "database hobbyists" who had no formal training in database design or best practices. They would take their monstrosities as far as they could go before ultimatley it stopped working or the person that wrote it left the company. At that point it would become the resident DBA's problem to support it as a Live application. So when I first heard of Power Pivot, a sense of Deja Vu overtook me and I felt like the guy in the Ausin Powers movie , knowing the inevitable is coming but somehow unsure how to get out of the way. But when I eventually saw it in action, I quickly realised that it is a very powerful tool. It has a much smaller "time to market" than traditional BI architectures. Combined with the new features of Excel, some pretty impressive dashboards can be produced.Of course PowerPivot is not a magic bullet and along with potential scalability issues there are the usual issues such as master data management and data quality that cannot be overcome easily with power pivot. As a tool though, it has potential. Traditional BI is expensive, both in terms of time and the amount of resources it takes to deliver the system. The time lag between an analyst or a commercial accountant requesting reports and the report being delivered can make a huge commercial difference. I have observed companies where empowered end users become extremely productive when allowed to plough in to various disperate datasets. It may not be the correct way or the most sustainable but its cheap and quick. In these times when budgets are being slashed and we are forced to deliver more with less, why not empower the end user in a tool that is designed for exactly this task.... @blakmk

  • Microsoft Access as a Weapon of War

    - by Damon
    A while ago (probably a decade ago, actually) I saw a report on a tracking system maintained by a U.S. Army artillery control unit.  This system was capable of maintaining a bearing on various units in the field to help avoid friendly fire.  I consider the U.S. Army to be the most technologically advanced fighting force on Earth, but to my terror I saw something on the title bar of an application displayed on a laptop behind one of the soldiers they were interviewing: Tracking.mdb Oh yes.  Microsoft Office Suite had made it onto the battlefield.  My hope is that it was just running as a front-end for a more proficient database (no offense Access people), or that the soldier was tracking something else like KP duty or fantasy football scores.  But I could also see the corporate equivalent of a pointy-haired boss walking into a cube and asking someone who had piddled with Access to build a database for HR forms.  Except this pointy-haired boss would have been a general, the cube would have been a tank, and the HR forms would have been targets that, if something went amiss, would have been hit by a 500lb artillery round. Hope that solider could write a good query :)

  • NHibernate Tools: Visual NHibernate

    - by Ricardo Peres
    You probably know that I’m a big fan of Slyce Software’s Visual NHibernate. To me, it is the best tool for generating your entities and mappings from an existing database (it also allows you to go the other way, but I honestly have never used it that way). What I like most about it: Great support: folks at Slyce always listen to your suggestions, give you feedback in a timely manner, and I was even lucky enough to have some of my suggestions implemented! The templating engine, which is very powerful, and more user-friendly than, for example, MyGeneration’s; one of the included templates is Sharp Architecture; Advanced model validations: it even warns you about having lazy properties declared in non-lazy entities; Integration with NHibernate Validator and generation of validation rules automatically based on the database, or on user-defined model settings; The designer: they opted for not displaying all entities in a single screen, which I think was a good decision; has support for all inheritance strategies (table per class hierarchy, table per class, table per concrete class); Generation of FluentNHibernate mappings as well as hbm.xml. I could name others, but… why don’t you see for yourself? There is a demo version available for downloading. By the way, I am in no way related to Slyce, I just happen to like their software!
