  • UML or design tools for websites

    - by Malfist
    What is a good tool to design the implementation of websites? I typically use UMl to design applications, but I feel that does not apply well to websites, specifically the heavy emphasis on UI that websites require. What would be a good tool to use to plan a webpage?

  • design a large scale network for an organization

    - by Essam
    i want to design a large scale network for an organization with HQ and two branches. i want to use a class A subnet. if i am using the network address 30.0.0.0 for the whole organization how can it be different from another organization company or whatever which is using the same address in another country? now i have the three locations for this organization,so i need 5 subnets [one for the HQ,two for branch A and branch B , one for connecting A to HQ and one for connecting branch B with HQ since i will use central DHCP server at the HQ,is that (number of subnetting) right? is it advisable to use class A or class B for this organization it term of address that will be wasted (let's say it is a university with two branches in two different states)?!

  • Online Collaborative Schema Design (leverage google docs?)

    - by AK
    I'm looking for an online, collaborative schema designer. It's important that it can handle revisions (history of changes). This looks cool, and I could host it on a server - but doesn't look like it would handle multi-user: http://ondras.zarovi.cz/sql/demo/ Currently we're doing a lot of design collaboration on google docs/spreadsheets. Has anyone had any success using google spreadsheet for schema design? Even if there were just a gadget for drawing lines/connections, I might give Google Docs a shot.

  • Is it possible to use ASP.NET Dynamic Data and SubSonic 3?

    - by James
    Is it possible to use ASP.NET Dynamic Data with SubSonic 3 in-place of Linq to SQL classes or the Entity Framework? MetaModel.RegisterContext() throws an exception if you use the context class that SubSonic generates. I thought I remembered coming across a SubSonic/Dynamic Data example back before SubSonic 3 was released but I can't find it now. Has anyone been able to get this to work?

  • What schema documentation tools exist for PostgreSQL

    - by Brad Koch
    MySQL has MySQL Workbench for designing and documenting your schema, and generates CREATE and ALTER scripts based on your design. We're looking at migrating to PostgreSQL in the near future, and we do need a practical way of documenting and modifying the schema structure. What similar tools exist for Postgres (that are OS X/Linux compatible)? Alternatively, what equivalent conventions would be followed for designing and documenting the structure of your Postgres database?

  • Web application design with distributed servers

    - by Bonn
    I want to build a web application/server with this structure: main-server sub-server transaction-server (create, update, delete) view-server (view, search) authentication-server documents-server reporting-server library-server e-learning-server The main-server acts as host server for sub-server. I can add many sub-servers and connect it to main-server (via plug-play interface maybe), then it can begin querying data from another sub-servers (which has been connected to the main-server). The sub-servers can be anywhere as long as connected to internet. The main-server can manage all sub-servers which are connected to it (query data, setting permission between sub-servers, etc). The purpose is simple, the web application will be huge as the company grows, so I want to distribute it into small connected plug-able servers. My question is, does the structure above already have a standardized method? or are there any different views? what are the technologies needed? I need a lot of researches before the execution plan begin. thanks a lot.

  • How do I pass a string or data object between two view controllers?

    - by Jonathan
    In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack: http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?

  • Using SOUNDEX and DIFFERENCE to Standardize Data in SQL Server

    My client wants to standardize address information for existing and future addresses collected for their customers, particularly the street suffixes. The application used to enter and collect address information has the street suffix separated from the address field, but it is a textbox instead of a drop down list therefore things are not standardized. I know there are some options out there to standarize data, but they would like a less expensive alternative. Are there any functions in SQL Server that I can use to standardized data?

  • Master Data Management Update

    Oracle's Master Data Management suite has seen remarkable development progress in the past year and a half. Leveraging out-of-the-box integration to applications provided by Application Integration Architecture, the cost, risk and time it takes to implement an MDM solution has been cut in half. Oracle Applications are now 'MDM Aware', Data Quality tools have reached state-of-the-art status, and new hubs are coming on line. In this AppsCast, Pascal Laik, VP MDM Products discusses this progress, what it means for Oracle customers, and where we are going from here.

  • How do we provide valid time estimates during Sprint Planning without doing "too much" design?

    - by Michael Edenfield
    My team is getting up to speed with Scrum, but most of us are more familiar with non-agile or "pseudo-"agile methodologies. The part that is the biggest hurdle for us is running an efficient Sprint Planning meeting where we break our backlog items into tasks, and estimate hours. (I'm using the terminology from the VS2010 Scrum Template; apologies if I use the wrong word somewhere.) When we try to figure out how long a task is going to take, we often fall into the trap of designing the feature at the code level -- table layout, interfaces, etc -- in order to figure out how long that's going to take. I'm pretty sure this is not the appropriate place to be doing that kind of design. We should be scheduling tasks for these design meetings during the sprint. However, we are having trouble figuring out how else to come up with meaningful estimates for the tasks. Are there any practical habits/techniques/etc. for making a judgement call about how long a feature is going to take, without knowing how you plan to implement it? If our time estimates are going to change significantly once the design has been completed, how can we properly budget our Sprint backlog ahead of time? EDIT: Just to clarify, since some of the comments/answers are very valid but I think addressing the wrong question. We know that what we're doing is not right, and that we should be building time into the sprint for this design. Conceptually all of the developers understand that. We also also bringing in a team member with Scrum experience to keep us on track if we start going off into the weeds. The problem is that, without going through this design process, we are finding it difficult to provide concrete time estimates for anything. We are constantly saying things like "well if we design it this way it might take 8 hours but if we end up having to do this other way instead that will take about 32 but it might not be as bad once we start trying to write it...". I also assume that this process will get better once we have some historical velocity to work from, but many of the technologies and architectural patterns we are using are new to us. But if potentially-wildly-wrong estimates are just a natural part of adapting this process then we will just need to recondition ourselves to accept that :)

  • What's the best way to keep java app data stored redundantly in a file?

    - by Bijan
    If I have systems that are based on realtime data, how can I ensure that all the information that is current is redundantly stored in a file? So that when the program starts again, it uses this information to initialize itself back to where it was when it closed. I know of xstream and HSQLDB. but wasn't sure if this was the best option for data that needs to be a literal carbon copy.

  • AWS EC2 Oracle RDB - Storing and managing my data

    - by llaszews
    When create an Oracle Database on the Amazon cloud you will need to store you database files somewhere on the EC2 cloud. There are basically three places where database files can be stored: 1. Local drive - This is the local drive that is part of the virtual server EC2 instance. 2. Elastic Block Storage (EBS) - Network attached storage that appears as a local drive. 3. Simple Storage Server (S3) - 'Storage for the Internet'. S3 is not high speed and intended for store static document type files. S3 can also be used for storing static web page files. Local drives are ephemeral so not appropriate to be used as a database storage device. The leaves EBS which is the best place to store database files. EBS volumes appear as local disk drives. They are actually network-attached to an Amazon EC2 instance. In addition, EBS persists independently from the running life of a single Amazon EC2 instance. If you use an EBS backed instance for your database data, it will remain available after reboot but not after terminate. In many cases you would not need to terminate your instance but only stop it, which is equivalent of shutdown. In order to save your database data before you terminate an instance, you can snapshot the EBS to S3. Using EBS as a data store you can move your Oracle data files from one instance to another. This allows you to move your database from one region or or zone to another. Unfortunately, to scale out your Oracle RDS on AWS you can not have read only replicas. This is only possible with the other Oracle relational database - MySQL. The free micro instances use EBS as its storage. This is a very good white paper that has more details: AWS Storage Options This white paper also discusses: SQS, SimpleDB, and Amazon RDS in the context of storage devices. However, these are not storage devices you would use to store an Oracle database. This slide deck discusses a lot of information that is in the white paper: AWS Storage Options slideshow

  • finding houses within a radius

    - by paul smith
    During an interview I was asked given the following: A real estate application that lists all houses that are currently on the market (i.e., for sale) within a given distance (say for example the user wants to find all houses within 20 miles), how would you design your application (both data structure and alogirithm) to build this type of service? Any ideas? How would you implement it? I told him I didn't know becaue I've never done any geo-related stuff before.
