JPA generalizes the POJO (Plain Old Java Object) model of object persistence with a set of interfaces and factories that are independent of the underlying provider by applying the Abstract Factory pattern. This allows you to choose Hibernate as your provider, for example, or switch to other providers without impacting the persistence layer code. JPA standardizes all persistence layer requirements: simple or complex mappings and JPQL language for object queries.
