Association
An association models a relationship between concepts that is not covered by another, more specific relationship.

An association relationship is always allowed between two elements, or between a relationship and an element.

The association relationship can be used when drawing a first high-level model where relationships are initially denoted in a generic way, and later refined to show more specific relationship types. In the metamodel pictures, some specific uses of the association relationship are explicitly shown.
