Aggregation

Aggregation is a special form of association that models the "part-whole" or "a-part-of" relationship as an aggregate (the whole) and parts. The most important property of aggregation is transitivity, i.e.  If X is part of Y and Y is part of Z, then X is part of Z. Aggregation should consider as a relationship in which an assembly class is related to component class. As component objects are not having different existence, they depend on composite objects as you can see in Figure Exam Schedule is not having separate existence.
