PointBase Introduces Competitive Replacement Program for Enterprise and Departmental Database Licenses

SANTA CLARA, CALIFORNIA – PointBase, a division of DataMirror and the leader in Java™ data management and synchronization solutions, today announced a new competitive replacement program that provides significant cost savings on enterprise database licenses. The EnterPoint License Program, available until July 31st 2004, allows organizations to acquire an unlimited enterprise or departmental PointBase license for internal use and save on costly upgrade, maintenance and new license fees from traditional database vendors.

"Today, many CIO's and IT executives understand they don't need to pay the full cost of a traditional enterprise database for 30-45% of their internal applications,' says Nigel Stokes, CEO, DataMirror. "Based on our experience in the embedded and mobile database market, we recognize the costs savings that are possible by implementing a scalable, pervasive database for internal business applications. The EnterPoint License Program lets organizations take full advantage of Java portability across their business, while allowing them to experience real cost savings, in some cases millions of dollars, on upgrades, new licenses and maintenance associated with traditional databases. Customers understand that the portability, speed, and zero cost administration that PointBase provides can really reduce the costs of running internal applications over traditional SQL compliant databases.'
