Informatica PowerCenter to help enable federal agency improve capabilities related to performance analysis, operations decision analysis, and financial management reporting

REDWOOD CITY, Calif., December 3, 2001 - Informatica Corporation (NASDAQ: INFA), the leading provider of enterprise analytic software, today announced that the Internal Revenue Service (IRS) has chosen Informatica PowerCenter, the company's data integration platform, to extract and integrate critical data for analysis in support of modernizing IRS tax processing and internal management systems.

The objective of the IRS internal management systems modernization is to improve its capabilities related to agency-wide performance analysis, operations decision analysis, and internal/external financial management reporting. Informatica PowerCenter is one of the solutions that will be deployed as part of one IRS Business Systems Modernization project, the Enterprise Data Warehouse (EDW)/Custodial Accounting Project (CAP), to meet this objective.

Informatica PowerCenter is planned for use in the development and implementation of data transformation interfaces between the DB2 mainframe warehouse and the IRS revenue general ledger system. It will also be used as the data aggregation interfaces between the DB2 mainframe warehouse and an Oracle Sun Solaris data mart. Further, Informatica PowerCenter is intended to integrate data from approximately 20-30 tax operations and internal management systems into a data warehouse, and then aggregate the data to populate an additional 5-7 data marts used by tax operations and internal management managers.

Informatica PowerCenter is intended to handle the following EDW/CAP processes:

• Taxpayer Account Processing Statistics. During the weekly extract cycle, Informatica PowerCenter is designed to aggregate taxpayer account processing statistics (e.g. number of refund transactions by service center) and load the data into the warehouse.
• Revenue Data Mart. On a weekly basis, the data integration platform is designed to aggregate tax revenue, refund, receivable and payable data from the warehouse and load it into the Revenue Data Mart to support the repetitive, predictable management analysis/reporting.
• Revenue General Ledger. On a daily basis, Informatica PowerCenter is intended to extract revenue accounting summary transaction (RAST) data from the warehouse. PowerCenter is also designed to transform the RAST data into journal voucher data and create an output flat file that can be imported into the Revenue General Ledger System (RGLS). After RGLS has processed the journal vouchers, it is planned for the data integration platform to extract journal voucher status data from RGLS to determine which of the journal vouchers did and did not post. For journal vouchers that did post, it is planned for Informatica PowerCenter to update the RAST records in the warehouse with the journal voucher ID and posting date.

“The IRS is in the process of modernizing its tax processing and internal management systems as part of the Business Systems Modernization effort, to provide U.S. taxpayers with the highest levels of service,” said Diaz Nesamoney, president and COO of Informatica Corporation. “We are extremely pleased to provide a technology to the IRS that will ultimately help increase efficiency within the organization and offer greater service to citizens.”
