Changing Entity Data

The Entity Framework and WCF Data Services use conceptual models to translate object operations into database operations. By using conceptual models, you can create, update, and delete data in your objects without knowing the schema of the database. When you need more control over database operations, you can use stored procedures to specify how your entities are stored, updated, and deleted.

The following topics show how to create, update, and delete data by performing operations on entities.
