The Ozone Database Project is a open initiative for the creation of an open source, Java based, object-oriented database management system.

You are welcome to join the project by writing code, discussing ideas, or just using the software and giving us feedback. Subscribe the mailing list!

ozone is a fully featured, object-oriented database management system completely implemented in Java and distributed under an open source license. The ozone project aims to evolve a database system that allows developers to build pure object-oriented, pure Java database applications. Just program your Java objects and let them run in a transactional database environment.

ozone includes a fully W3C compliant DOM implementation that allows you to store XML data. You can use any XML tool to provide and access these data. Support classes for Apache Xerces-J and Xalan-J are included.

Besides the native API, ozone provides a ODMG 3.0 interface. Although not fully ODMG compliant it helps you to port applications to/from ozone.

ozone does not depend on any back-end database or mapping technology to actually save objects. It contains its own clustered storage and cache system to handle persistent Java objects.
