In the last chapter we took a very quick look at the bits and pieces that comprise Entity Framework and an Entity Framework application, but we spent most of the time exploring the rules of relational database design and how they differ from Object-Oriented Analysis & Design. (Otherwise known as, the impedance mismatch that Entity Framework addresses.)
In this chapter we’ll begin our exploration of Entity Framework proper with an extended walkthrough, building a model from the database design we looked at in the last chapter. (It’s easy: Entity Framework does most of the work.)
Once we have the model in place, we’ll back up a bit and look at the Entity Data Model (EDM) and code files that the wizard created for us.
