For each association :

- The multiplicity (1, 0..1, *) is displayed for some associations. This determines the range of linkable objects.
- A white circle at the end of an association indicates which is the major object in the association, i.e., the object which is modified in case the association is removed.
- A black diamond at the end of an association indicates that the other object is a component of the major object. It is a strong association between the two objects. When the major object is deleted, all is components are also deleted.
