Java Data Objects (JDO) is a specification from Sun Microsystems for the transparent persistence of Java objects to any transactional datastore. This document provides an overview of JDO. The information presented applies to all JDO implementations, unless otherwise noted.


For coverage of Kodo's many extensions to the JDO specification, see the Reference Guide.

1.1. Intended Audience

This document is intended for developers who want to learn about JDO in order to use it in their applications. It assumes that you have a strong knowledge of Java and object-oriented concepts, and a familiarity with the eXtensible Markup Language (XML). This document does not, however, assume any experience with database programming or the manipulation of persistent data in general.
