Association vs Aggregation vs Composition, one of the easy Object Oriented Programming concepts.
Association: has-a relationship between A & B without no ownership and no life-cycle control
Aggregation: has-a relationship between A & B with ownership and but no life-cycle control
Composition: has-a relationship between A & B with ownership and life-cycle control
