PALO ALTO, Calif., June 25, 2001 – Informatica Corporation (NASDAQ: INFA), the leading provider of business analytic solutions, today announced a strategic technology and marketing alliance with TIBCO Software Inc. (NASDAQ: TIBX).  As part of this alliance, Informatica will develop an adapter to integrate TIBCO’s enterprise application integration (EAI) solutions with the Informatica PowerCenter data integration platform to provide Informatica customers with real-time analytics capabilities.

“By uniting event-driven transactional data with the Informatica platform, we’re helping customers take a critical step on the road to more efficient operations and better decision-making,” said Fred Meyer, chief marketing officer for TIBCO. “Just as TIBCO enables diverse applications to communicate in real time, Informatica enables timely judgments to be made based on the aggregation of this information via real-time analytics.”

The TIBCO and Informatica alliance will enable streams of real-time data from TIBCO’s EAI infrastructure software to be captured and integrated with historic “time slice” data through the Informatica PowerCenter data integration and analysis platform.

Enhanced for real-time analytics, Informatica PowerCenter will (1) instantaneously source real-time data from EAI data streams, message queues and related sources, (2) integrate that data with other information from across the enterprise and (3) deliver real-time analytics, including alerts, to relevant applications and personal information devices to drive immediate actions.

 “Real-time analytics is the logical next step for the analytic solutions industry,” said Girish Pancha, senior vice president and general manager of platform technologies at Informatica. “ We are working with TIBCO’s leading solutions to address this market opportunity, providing our customers with a competitive, early-mover advantage across a wide range of business applications, from CRM to supply chain management.”

In addition to product development, Informatica and TIBCO will also collaborate on joint marketing and sales activities.  The TIBCO/Informatica connectivity solution is scheduled for release by Informatica in the third quarter of 2001.
