Press Releases - 2004

JAVAONE, SAN FRANCISCO, CA, – (June 29, 2005) - DataMirror® (Nasdaq: DMCX; TSX: DMC ) today announced the availability of DataMirror PointBase 5.3®, DataMirror's full-featured, SQL92/99 JDBC compliant Java relational database. Enhanced in response to OEM customer requirements, PointBase 5.3 delivers new features that further improve the solution's scalability, performance, and functionality. PointBase 5.3 benefits users by lowering the cost of database development, reducing the time to market and facilitating integration between Java applications and back-office systems. To date, more than 100 of DataMirror's 2,000 clients have adopted PointBase for their Java database needs.

PointBase 5.3 enhancements include:

• Larger data type support - Enables applications to perform more precise operations by providing expanded data type support for mobile platforms and allowing mobile applications to store and manage a greater range of data in the PointBase database.
• Enhanced query performance - Changes to the autonomic cost-based optimizer that improves the performance of range-predicated queries and overall database query performance without user configuration.
• Greater application control - Applications can fine tune PointBase performance and enhance the end-user experience by making it easier for applications to manage PointBase interactions in concurrent data access situations. By explicitly locking database tables, applications featuring PointBase 5.3 are able to reduce deadlocks and wait times.
• Parallel reads/writes - Applications that perform a large number of database changes can further improve PointBase performance by leveraging the power of parallel disk IO to separate physical storage devices for log and data read/write operations.
• Database auditing support - PointBase now supports DataMirror LiveAudit®, DataMirror's complete, multi-platform database auditing solution for organizations that are obligated to fulfill data audit trail requirements for compliance, security and internal control purposes. With database auditing support, application developers using PointBase 5.3 can provide out of box auditing solutions with DataMirror LiveAudit.
