Best answer 29 29 votes ans is (b) Aggregation Aggregation is a special case of association. A directional association between objects. When an object ‘has-a’ another object, then you have got an aggregation between them. Direction between them specified which object contains the other object. Aggregation is also called a “Has-a” relationship. kvkumar answered Jun 29, 2016 • selected Jul 2, 2016 by pC kvkumar comment Share Follow 0 reply Please log in or register to add a comment.
