JPA is all about POJOs and all relationships are managed as associations between POJOs. All JPA implementations are based on best practices that complement an ideal POJO based domain model. In the first part of this series, I had talked about immutable entities, which prevent clients from inadvertent mutation of the domain model. Mutation mainly affects associations between entities thereby making the aggregate inconsistent. In this post, I will discuss some of the gotchas and best practices of abstracting associations between entities from client code making your domain model much more robust.
