SANTA CLARA, Calif.--(BUSINESS WIRE)--April 6, 2004

PointBase Embedded Provides Single Database Support for

Application Development & Testing

PointBase, the leader in Java(TM) data management and synchronization solutions, today announced that Unify Corporation, a global enterprise software company, has selected PointBase Embedded for use in its Java-based application platform. PointBase Embedded is used within the Unify NXJ(TM) Design Center, in which developers design and test applications for deployment on the Unify NJX  platform.

The Unify NXJ application platform delivers process-driven transactional applications in an easy, powerful and open integrated platform solution. Unify NXJ's business process management, reporting, enterprise application and portal integration, and advanced application capabilities help organizations effectively deliver real-time, adaptive enterprise applications that run on the J2EE platform.

"Prior to implementing the PointBase solution, all local development, testing, tutorials, and sample applications were run on multiple databases. This process proved to not only be too cumbersome to manage, but was impractical for developers," says Dave Glende, CTO, Unify. "With PointBase Embedded, we are able to provide a unified database solution to offer a better out-of-the-box experience within the Unify NXJ Design Center. Moreover, we have minimized internal research and development time, and are making more efficient use of our product development and licensing funds."

"Unify joins the many customers who have realized the benefits of embedding a comprehensive relational database within their product offering. PointBase Embedded's ease-of-installation and robust, intuitive functionality allows Unify customers to experience seamless, out-of-the-box application development, resulting in the simplified and accelerated delivery of applications," says Nigel Stokes, CEO, DataMirror.
