Association Classes
An association class is an association that also has class properties as attributes.
It is helpful to create an association class in order to specify the characteristics of an association.
For example, the quantity of the requested product needs to be specified on each order line.
To create an association class:
1. Create a new class.
2. Using the Link button, create a link between the class and the association.
The association class is linked to the association by a dotted line.
*As for standard classes, it is possible to hide the compartments and resize the association class using the Display command in its pop-up menu.
