REDWOOD CITY, Calif., July 23, 2004 -- Informatica Corporation (Nasdaq: INFA), a leading provider of data integration software, today announced that it has been named the worldwide revenue market leader in data warehouse integration software for the fourth year in a row by IDC, a leading provider of global IT research and advice. A new report, entitled "Worldwide Data Warehousing Tools Forecast 2004 - 2008 and 2003 Vendor Shares," identifies Informatica as the market leader with a 17.4 percent share, highlighting the company's strong revenue increase of 11.8 percent in 2003 and successful strategy of "re-focusing on its core data integration and replication business."

"Data warehousing serves a pivotal role in supporting both strategic and operational decision-making processes," said Dan Vesset, research director of IDC's Analytics and Data Warehousing program. "Users are now looking for access to data from more sources, new types and combinations of information, and ensured data quality -- all of which spell increased opportunities for warehouse generation software vendors."

IDC defines warehouse generation tools as "software used in the design, cleansing, transformation, loading, and administration of the data warehouse." In 2003, the data warehousing tools market experienced 11 percent growth, more than three times the growth rate of the previous year. Forecasting a five percent compound annual growth rate through 2008, the new IDC report projects that the market for such tools -- including data movement and integration software -- will exceed one billion dollars in 2005.

"As the IDC report asserts, users will increasingly demand solutions that combine batch and real-time data integration, integrated data quality tools, and scalability to support more complex querying and growing user populations -- areas in which Informatica already excels," said Paul Albright, executive vice president and chief marketing officer at Informatica. "Combined with our product vision for delivering a Universal Data Services architecture and our marquee customer base, Informatica is well positioned for continued success and market leadership in the expanding data integration and data warehousing markets."

The IDC report further validates Informatica's leadership position. Computer Business Review (CBR) earlier this month selected Informatica as one of the ten most-influential companies in the data integration market for the second year in a row.
