How closely does your data model map to your UI and domain model? The data model can be quite close to the domain model if it has, for example, a Customer table, an Employee table etc. The UI might not reflect the data model so closely though - for example, there may be multiple forms, all feeding in bits-and-pieces of Customer data al...

I want to abstract a large database store (relational, OLTP) from the application layer by having the application consider the database as a service. The natural way of doing this is by calling sprocs, but tradit...
We have been asked by a client to incorporate ICD-9 codes into a system. I'm looking for a good resource to get a complete listing of codes and descriptions that will end up in a SQL database. Unfortunately a web service is out of the question as a fair amount of the time folks will be off line using the application. I've found http...

I have a tree of data that I would like to present to the user in a top-down manner, the way you see parse trees presented. Conceptually, the data have a lot in common with what an NSOutlineView would present: hierarchical structure, tree nodes can be be expanded and reordered, etc. I'm trying to figure out how I might be able to manip...
I'm reading up on Google App engine and I'm thinking of using it as a CDN for a project I'm working on. As far as I can tell, there's two ways to store data. I could use a datastore or I could put files in a directory. I was brought up believing it's a bad idea to store large binary data in a database, but according to Google, the dat...

I have to build a web application in Silverlight. This application is entirely data centric with SQLServer 2008 as the database. What are different ways of handling this design problem?

I have an application which utilizes graph (tree-like) custom structures. The structures are not real trees, but pretty much everything is connected together. The quantity of the data is also big (millions of nodes can exist). Tree-nodes can vary in type to make it more interesting (inheritance). I don't want to alter the data-structures...
