Question

Quizplus · Accepted Answer

UML uses both cardinality and aggregation relationship, but they are not interchangeable terms. Cardinality refers to the number of instances of one class that are associated with instances of another class, while aggregation relationship refers to a specific type of association where one class (the whole) contains parts that may still exist independently.
