The appendix provides an overview of the ADO.NET
Entity Framework, including some background and some examples of how it can be used to benefit
today??™s developers.
The ADO.NET Entity Framework has been scheduled to release after the release of Visual Studio 2008.
At the time of this writing the current release of the Entity Framework is the ADO.NET Entity
Framework Beta 2 dated August 27, 2007.
Overview
Today, the primary method of accessing data in a relational database is to write code that
accesses that data directly. This requires developers who are used to working in an OO (objectoriented)
environment to know the relational storage schema and takes much more code than is
really needed.
The goal of the ADO.NET Entity Framework is to give developers the capability to create
applications that access data in an OO fashion, meaning developers can now use a conceptual
model in which to work with objects and properties. The benefits of this are much less code to write
and developers who can work with technology that they know without needing to know the exact
schema (such as tables and columns) in the underlying database.
