Aggregate In Domain Driven Design . Aggregate a cluster of associated objects that are treated as a unit for the purpose of data changes. I have a question related to relationships between aggregates in domain driven design.
What Are Aggregates In DomainDriven Design? James Hickey from www.jamesmichaelhickey.com
For example we can have many entities and value objects nested in aggregate. An aggregate is a consistency boundary that decomposes large models into smaller clusters of domain objects that are technically easier to manage. Aggregates are groupings of related objects.

What is more, we cannot correctly reason on aggregate design without applying transactional analysis. Those with experience in ddd might understand what that means and why it applies. Its duty is to explicitly group the domain objects that are designed to support the behaviors and invariants of a domain model while acting as a consistency and transactional boundary. Between pos we can have eventual consistency, since we are comfortable with not trying to.
