UML14 — Dependencies (and other relationships) with role ends

Summary: Dependency relationship in UML does not have role ends, similar to the association ends that associations have. Therefore, it is not possible to specify, for example, that:

1. an entity depends on an ordered set of other entities.
2. an entity depends on a specified number of instances of other entities
3. the roles of the entities that participate in the dependency. Dependency imply the entity roles "client" and "supplier". However, I often came across situations where I needed to specify more concrete roles than "client" and "supplier". In cases I came across, replacing dependencies by associations was not a convenient solution.
