Querying Data Through a Conceptual Model

When you use a conceptual model to describe the data in a database, you can query data through your objects instead of having to translate back and forth between a database schema and an object model.

You can use conceptual models with Entity Framework and WCF Data Services applications. The following topics show how to query data through a conceptual model.
