RE: What is aggregation in UML?
Aggregation is a special type of ‘has-a’ relationship between classes where one of the two participating classes is part of other one. I.e. it’s a ‘whole-part’ relationship. The class acting as ‘whole’ always has multiplicity of one.

 In UML representation, aggregations are represented by an association that shows a rhomb on the side of the whole.

For example, A car has Wheels.

Composition is a special type aggregation where the 'has-a' relationship is more strong. I.e. the part entity cannot exist without the whole entity. For example, an university has departments, which cannot exist on their own with the containing 'university' entity.
