Uml Association End Role Properties. An explicit role name is not required - it is useful when the role of the object is not clear. In particular relationships in class diagrams include different types of logical connections.
In UML diagrams an association class is a class that is part of an association relationship between two other classes. The derived link from Association to EndType is derived from the type of the Properties in the memberEnds. A role name identifies an end of an association and ideally describes the role played by objects in the association.
An association represents the relationships between classes 12 p.
A link end similar to an association end is an endpoint of a link and connects the link to an object. This can be expressed in a class diagram by placing a small dot at the B side of the association called an association end ownership dot in UML. The Association Role metamodel describes our second role pattern. In the case of an association end context is the set of types at the other end or ends of the association.
