[[Repository|Repositories]] abstract the persistence logic of [[Aggregate|Aggregates]]. Aggregates group related [[Entity|Entities]] and [[Value Object|Value Objects]], ensuring [[Transactional consistency]], protecting invariants, and enforcing business rules. Making Repositories dependent on or referencing other Repositories can break the encapsulation of each Aggregate. Interactions between Aggregates should be handled at a higher level, typically through [[Domain Service|Domain Services]] or [[Application Service|Application Services]], which can coordinate Repositories without compromising Aggregate encapsulation. By keeping Repositories independent, they become easier to test, as their behavior remains isolated from the persistence concerns of other Aggregates.
