The best definition of an aggregate comes from Eric Evans and his DDD book; in it, he says: An "aggregate" is a cluster of associated objects that we treat as a unit for the purpose of data changes." - Evans. 126 Let's break that apart a bit. object collaboration design. Aggregate is a pattern in Domain-Driven Design. A DDD aggregate is a cluster of domain objects that can be treated as a single unit. An example may be an order and its line-items, these will be separate objects, but it's useful to treat the order (together with its line items) as a single aggregate.

In the context of building applications, DDD talks about problems as domains.
