In the software development process, a reference implementation (or, less frequently, sample implementation or model implementation) is the standard from which all other implementations and corresponding customizations are derived.An improvement to a reference implementation reflects an unchanging specification.rom Wikipedia, the free encyclopedia.

An important capability of the Java Persistence API is its support for inheritance and polymorphism, something that was not available in EJB 2.1. You can map a hierarchy of entities, where one entity subclasses another, to a relational database structure, and submit queries against the base class.he EJB 3.0 example illustrates inheritance from an entity. However inheritance from POJOs that are not entities -- for behavior and mapping attributes -- is also allowed. The base entity or nonentity can either be abstract or concrete.
