- The UML explains the mechanics of this interaction by means of the relationships it defines.
- The relationships are classified as under:
External links
- Basic relationship among objects.
Association
- Family of links
Aggregation
- A variant of the "has a" relationship.
- It is an association that represents a part- whole or part-of relationship.
