TORONTO--(BUSINESS WIRE)--Dec. 16, 2002

Growing Number of Manufacturing Companies Select

DataMirror LiveBusiness(TM) Solutions

DataMirror (Nasdaq: DMCX) (TSX: DMC), the leading provider of enterprise application integration and resiliency solutions, today announced that a growing number of manufacturing companies are gaining competitive advantage through DataMirror's real-time data integration and resiliency solutions that enhance operational efficiencies, streamline supply chains and lower the cost of business transactions.

Recent customers Garan Inc., Hitachi Automotive Products (USA) Inc., The Paper Magic Group Inc. and Sauder Woodworking join a long list of leading manufacturers who have implemented DataMirror software. Other customers include: 3M Company, Acushnet Company, Corning, Duracell USA, General Semiconductor, The Gillette Company, The Goodyear Tire & Rubber Company, Ingersoll-Rand, Maytag Appliances and W.L. Gore & Associates.

"When you're talking about your supply chain, what you can't see can hurt you. Real-time data integration allows manufacturers to streamline operations and quickly identify weak links or bottlenecks before they impact business," says Nigel Stokes, CEO, DataMirror. "In addition to monitoring critical business activities and protecting the continuity of supply chains, DataMirror solutions also allow manufacturers to effectively communicate vital data in real-time such as pricing updates to the channel and sales people in the field. Our out-of-the-box solutions help customers achieve better supply chain visibility, improved operational efficiencies and high cost savings-all factors that impact the bottom line."

"The diverse mix of packaged and custom ERP and SCM applications employed by manufacturers are treasure chests of data that businesses need for analytic solutions that drive business performance," says Doug Laney, META Group Vice President, Application Delivery Strategies. "However, the challenges of multi-platform integration have made these data assets difficult to access. Data integration solutions with peer-to-peer architectures, multi-platform support and real-time capabilities can enable rapid enterprise-wide data integration for manufacturers. Also, our research indicates that graphical administration consoles utilizing Java to provide commonality and portability, can reduce total cost of ownership."

DataMirror's LiveIntegration(TM) solution connects employees, suppliers and distributors to real-time flows of information-regardless of the different systems, applications and relational databases deployed across the enterprise. No costly programming is required to integrate data across multi-platform environments. DataMirror's complementary LiveResiliency(TM) solution provides the ability to continuously mirror critical data and applications, and automatically switch users from primary to recovery systems in the event of an outage. LiveResiliency enables operational and customer-facing systems to be thoroughly backed up and resilient 24/7 and ensures that internal systems connected to trading partners, suppliers and distributors are always available. Creating a real-time, zero-latency enterprise that is virtually impervious to downtime is a definitive competitive advantage for manufacturers.
