DataMirror Unveils PointBase 5.4.

TORONTO & SANTA CLARA, Calif. -- Enhancements substantially improve performance and scalability of mobile and embedded applications

DataMirror(R) (TSX:DMC), a leading provider of real-time data integration, protection and Java database solutions, today unveiled DataMirror PointBase 5.4, the latest release of DataMirror's secure, zero administration and full featured SQL92/99 JDBC-compliant Java relational database. PointBase 5.4 includes new performance, functionality and usability enhancements that make it easier for Java developers to accelerate development cycles and reduce development costs.

"Java developers are constantly looking for solutions that improve the performance and scalability for their mobile and embedded applications," said Lucian Mustatea, Vice President, Research & Development. "The new performance monitoring GUI, enhanced SQL query support and unrestricted MIDP storage size built into PointBase 5.4 enable developers to create applications for Palm (Nasdaq:PALM), RIM (Nasdaq: RIMM; TSX: RIM), and Symbian mobile platforms that are faster, larger, more efficient and responsive to users' needs."

PointBase 5.4 Highlights

The following new features are included in PointBase 5.4 for PointBase Embedded:

- Real-time Performance Monitoring - Developers can fine-tune the PointBase database and their applications using a built-in, easy-to-use graphical user interface (GUI) that monitors cache, memory, input/output (IO) and other crucial performance indicators in real time, resulting in greater insight, maximum flexibility and improved capacity planning;

- Enhanced SQL Query Support - The new release offers full support for CASE, NULLIF and COALESCE expressions in SQL queries, enabling developers to greatly simplify complex SQL queries, reduce errors and minimize the development effort; and,

The following new feature has been added to PointBase 5.4, Micro version:

- Unrestricted MIDP Storage Size - Unlike the limited capabilities of Record Management System (RMS) for local data storage, PointBase 5.4 can store an unlimited number of Mobile Information Device Profile (MIDP) records to greatly improve the functionality, memory and processing power of mobile phones, RIM's Blackberry, Palm's Trio and other MIDP devices. Developers of enterprise applications get much larger space requirements without worrying about managing multiple RMS record stores. Storage is limited solely to the size of the MIDP device.

DataMirror PointBase is a secure, zero administration and full featured SQL92/99 JDBC-compliant Java relational dataset. Versions include: PointBase Embedded for server application development; PointBase Micro, a compact database written for use in handheld devices; and, Transformation Server for Mobile for synchronizing data between databases residing on mobile platforms and corporate back-end databases. PointBase seamlessly integrates into Java development environments and application server tiers to help users build and deploy portable Web applications.
