Beyond Java ORM with Versant JPA (Part 1)
German Viscuso, Developer Relations Manager, Versant Corporation.
Abstract: The JPA specification draws on ideas, concepts and standards from leading persistence frameworks such as TopLink, Hibernate, and Java Data Objects (JDO), as well as on earlier EJB container-managed persistence. But JPA itself is just a specification; a set of interfaces, and requires an implementation and a database to persist to. The Versant team reviewed the state-of-the-art of JPA technology to bring to you Versant JPA, the JPA 2.0 provider for Versant Database technology. In this multi-part article I will introduce the basic building blocks of the Java Persistence API as I walk you through the Versant JPA implementation from a user (developer) perspective.
