Data Points: Designing an Entity Data Model

The Entity Framework is an exciting new technology for ADO.NET developers that enables you to view data using a logical model instead of a physical model. At the heart of the Entity Framework is the Entity Data Model (EDM), which defines the entity types, relationships and containers that developers interact with via code.

In the February issue of MSDN Magazine, John Papa demonstrates using XML and the design tools in Visual Studio 2008 to design an EDM that uses inheritance, invokes stored procedures, and models your business instead of writing code directly against your relational database schema.

Previously, in the January issue of MSDN Magazine, John discussed some best practices for data access strategies when developing mobile applications for Smartphones. He demonstrated how to design a data-driven Smartphone application that can communicate with a server application and both display and save data over the Internet.
