Creating an Association
To create an association:
1. Click the
Association button

in the objects toolbar.
2. Click one of the classes concerned and drag the mouse to the other class before releasing the button.
The association is indicated by a line in the diagram.
If there is already an association between the two classes, the Add an Association dialog box opens. It enables creation of a new association or selection from existing associations.
You can specify a name for the association in its Properties dialog box, accessed from its pop-up menu.
