Aggregation is a collection of objects where they are loosely associated with each other. Composition is when there is a tighter restriction between two, or more, objects where the composed object cannot exist without the other object, or objects.

Whats the difference between aggregation and composition?

It's a subtle difference in how the words are used. Aggregation means putting things together. Composition means the discrete things which have been put together. You could ask "what is the composition of the ftse 100?" And the answer would be a list of companies. The question "what is the aggregation of the ftse" doesn't make sense. The ftse 350 is the aggregate of the ftse 100 and the ftse 250. It is composed of the ftse 100 and the ftse 250. A fund which tracked the ftse 350 might have the same composition as a fund which tracked the ftse 100 and the ftse 250
