ADONET Entity Framework

ADO.NET Entity Framework is a family of API’s for Microsoft’s .NET Framework. It is designed to provide data access interfaces starting with .NET Framework 3.5 and Visual Studio 2008.
Entity Framework defines objects called “entities.” An Entity Data Model (model of entity-relationships mapped to DataStore schema) permits items of data to be individually processed, independent of their underlying representations in a DataSet. Entity SQL has been developed for querying the Entity Data Model. The ADO.NET Entity Framework provides interfaces for accessing data for an Entity Data Model.
