Chapter 4 Building Conceptual Data Models

Creating an association in a CDM

There are several ways to create an association:

• From a diagram
• From the Browser
• From the list of associations

At creation, an association has a default name including a number. This number is assigned in the order of creation of objects.

For more information on the different ways to create an association, see section Creating an object in chapter Managing objects in the General Features Guide .

To create an association from a diagram:

1. Click the Association Link tool in the Palette.
2. Click inside the first entity and while continuing to hold down the mouse button, drag the cursor to a second entity. Release the mouse button.
   
   An association symbol is created between the two entities.
   
3. Double-click the new association symbol in the diagram to display the association property sheet.
4. Type an association name and an association code.
   
5. Click OK.
