Java Persistence API has two sides. The first is the ability to map objects to a relational database. Configuration by exception allows persistence providers to do most of the work without much code, but the richness of JPA also allows customized mapping from objects to tables using either annotation or XML descriptors. From simple mapping (changing the name of a column) to more complex mapping (inheritance), JPA offers a wide spectrum of customizations. As a result, you can map almost any object model to a legacy database.
