ADO.NET Entity Framework is an Object/Relational Mapping (ORM) framework that enables developers to work with various relational databases like SQL Server, Oracle, DB2, MYSQL etc. It enables developers to deal with data as business objects and entities. Using the Entity Framework, developers issue queries using LINQ, then retrieve and manipulate data as strongly typed objects using C# or VB.NET.
