Launched in 2005, this portal provides the most up-to-date collection of free materials on object database technology on the Internet. ODBMS.ORG was created to serve faculty and students at educational and research institutions as well as OO software developers in the open source community or at commercial companies. It is designed to meet the fast-growing need for resources focusing on object database technology, objects and databases, the integration of object-oriented programming and databases, persistent object life cycle management, and object oriented persistence technologies.
