DataMirror Introduces Dynamic ODS Business Solution.

TORONTO & SANTA CLARA, Calif. -- New Business Solution Continuously Feeds Operational Data Stores Without Affecting Performance of Production Systems

DataMirror(R) (NASDAQ: DMCX) (TSX: DMC) today introduced a dynamic operational data store (ODS) solution for companies with existing data warehouses whose data volatility and volume are impacting system performance. The new solution extends DataMirror's abilities to transform data warehouses into dynamic operational data stores and reinforces the company's commitment to help organizations make business decisions with the best available information.

By combining DataMirror's Dynamic ODS solution with production environments, companies will have the ability to add new data sources, eliminate performance issues and enable real-time information flows. DataMirror's scalable high performance Change Data Capture (CDC) technology immediately detects changes to source data and flows them into an ODS in real time.

"Data integration is an increasingly important topic, whether it be for populating operational systems or moving data into databases used for business intelligence applications," said Ted Friedman, Research Vice President, Gartner. "To deliver data integration architectures quickly and on-budget, organizations seek cost-effective data integration solutions that are easy to deploy in heterogeneous environments."

DataMirror's Dynamic ODS solution requires no changes to existing IT infrastructure, business applications or associated databases, and provides real-time data feeds from any operational system. The Dynamic ODS allows companies to leverage IT investments in ETL tools, applications and network architecture, and gain real time access to production data for business intelligence, BAM, or application testing and development.

"DataMirror has more than 2,000 customers who have gained a competitive advantage by using our data integration technology," said Stewart Ritchie, Senior Vice President, Worldwide Sales, DataMirror. "With the Dynamic ODS sales campaign, we're focusing our sales energy on an area where we know customers need help and where we see the greatest opportunity to create value."

DataMirror's Dynamic ODS solution allows companies to do more with their data without impacting mission-critical business applications. DataMirror's low-overhead CDC technology helps companies achieve real-time data integration without affecting the performance of existing systems.
