Binary Association shape

In a static structure diagram, a binary association  is a relationship between exactly two classes. You can add name and stereotype properties to a binary association. The point where a binary association connects to a class is called an association end or role. Properties related to a specific role, such as end name, multiplicity, aggregation, and navigability are attached to an association end.
