Acquisition broadens Informatica's enterprise data integration capabilities with mainframe connectivity and patented change data capture technology

REDWOOD CITY, Calif., September 29, 2003 - Informatica Corporation (NASDAQ: INFA), a leading provider of data integration and business intelligence software, today announced it has completed the acquisition of privately held Striva Corporation, an award-winning provider of mainframe data integration solutions. This acquisition extends Informatica's leadership in comprehensive enterprise data integration and business intelligence with Striva's innovative mainframe technology for high-speed bulk data movement and industry-leading solution for real-time change data capture in legacy and non-legacy environments.

According to recent research by Giga, a wholly owned subsidiary of Forrester Research Inc., the acquisition of Striva is further evidence of Informatica's commitment to deliver the most comprehensive data integration and business intelligence solutions.  The research, which can be viewed here, noted that Informatica's recently deepened OEM arrangement with the leading data cleansing vendor, Firstlogic, and its announcement of a new enterprise-scope metadata management product, SuperGlue, combined with this acquisition of sophisticated mainframe integration, all move Informatica in a very positive direction.
