A useful Entity Data Modelling Tutorial

One of the things I really liked about .NET 3.5 was the new LINQ to SQL framework. My interpretation was that LINQ provided a straightforward way to access your database tables, views and stored procedures using a first-order query language. No need to use DataSets, DataTables or ADO.NET connections – just setup your context and away you go!

I wasn't too enamoured with the Entity Data Modelling framework. I found it a bit difficult to use, and clunky to implement. Fortunately, Mendhak at CodeGuru has written what I think is a very useful tutorial that covers the basics of Entity Data Modelling. The very last page has a very useful summary clearly outlining the differences between LINQ to SQL and EDM which I found quite illuminating. EDM is used for Enterprise-level projects, LINQ to SQL is used for Rapid Application Deployment. Obviously the latter is more useful for my little project than the former.
