CHAPTER 3 ■ THE ENTITY DATA MODEL INSIDE AND OUT The Designer is the tool that allows you to work with the EDM and provides the functionality developers need to create, modify, and update the EDM. The Designer consists of several components to assist you in designing and editing your conceptual model. Figure 3-2 shows the different components, including the following: • • • • Designer surface: A visual surface for creating and modifying the conceptual model. Mapping Details window: The location where mappings are created or modified. The window is discussed later in the chapter.
