Java DB is lightweight at 2 megabytes and embeddable within desktop Java technology applications. The NetBeans integrated development environment (IDE) 5.0 also supports Java DB. Sun distributes Java DB in many of its products, including the Sun Java Enterprise System and the Sun Java System Application Server. Sun, IBM, other companies, and individuals have been actively involved in development of the relational database as part of the Apache Derby community. IBM donated the Derby product source code to the Apache Foundation as an open-source project. Derby was previously available under its earlier name, Cloudscape, from its former owners: Cloudscape, Informix, and IBM.

Sun Microsystems recently announced that it is distributing and supporting Java DB based on the 100 percent Java technology, open-source Apache Derby database.
