DataMirror Introduces Transformation Server/ES

BEA WORLD, SANTA CLARA, Calif.,--(CCNMatthews - Sept. 27, 2005) -

Real-Time Solution Flows Business Events to Message Queues in EAI, BPM and SOA Environments

DataMirror® (NASDAQ: DMCX - News; TSX: DMC - News) today launched Transformation Server/ES (Event Server), a solution for initiating the real-time flow of information throughout the enterprise. Transformation Server/ES detects events as they occur in mission-critical production applications and creates useful business information to feed into the message queues of leading enterprise application integration (EAI), business process management (BPM), and service-oriented architecture (SOA) environments. With Transformation Server/ES critical business events are never missed.

"The concept of events is the key underlying factor that will enable certain revolutionary improvements in business processes and application systems during the next five years," said Roy Schulte, VP Distinguished Analyst, Gartner.

Transformation Server/ES leverages DataMirror's low impact Change Data Capture (CDC) technology to connect natively to source databases running on any platform including Oracle, DB2, UDB and SQL Server. By reading changes directly from the database logs the database, application, and end users of mission-critical applications are not impacted.

Transformation Server/ES is a high-performance solution that integrates seamlessly with existing IT infrastructure. The solution enables real-time event awareness without the need for changes to databases, applications, middleware or hardware.

Transformation Server/ES features:

- Capture Events in Real-Time - DataMirror's scalable high performance Change Data Capture technology enables real-time event awareness by using database logs to immediately detect changes to source data and flow those changes to messaging middleware.

- Transform and Enrich Events - Event data is transformed and enriched before integration with the middleware layer. Composite transactions containing useful business information are created by combining data from key business events with historical content in a data warehouse, or business data in other applications. Data is pulled from heterogeneous systems and consolidated into a single event.

- Heterogeneous Platform Support - Transformation Server/ES integrates seamlessly with existing IT infrastructure. Real-time event awareness does not require database, application, middleware, hardware or operating system changes.

- Rich User Interface - An intuitive user interface makes it easy to setup and maintain the flow of useful business information from disparate data sources.

DataMirror will host a presentation at BEA World 2005 to demonstrate how Event Server integrates complex business events with BEA WebLogic and AquaLogic. Visit DataMirror at BEA World 2005, booth 141.
