THE WORLD'S LARGEST COMMERCIAL DATABASE RUNS ORACLE

Winter Corporation Survey Validates 29.2 Terabyte Oracle Data Warehouse

REDWOOD SHORES, Calif., Nov. 14, 2003 - Oracle Corp. (NASDAQ:ORCL) today announced that Oracle is the leading database for transaction processing and decision support in real-world customer environments, according to the Winter Corporation 2003 TopTen Program.

According to the survey, the largest commercial data warehouse in the world, with 29.2 terabytes of data, runs Oracle(r) Database. Overall, Oracle customers run the world's top 10 OLTP database implementations on Unix, both OLTP Sites by Database Size, and by Most Rows/Records.

The survey also found that the world's largest transaction processing database on Unix runs Oracle Database, with more than 5.0 terabytes of data. Worldwide, Oracle customers run three of the top 10 OLTP databases on Windows; the largest manages 3.2 terabytes of data. In addition, Oracle Collaboration Suite Email Server handles more than 2.2 terabytes of data.

The survey identifies the world's leading database implementations based on Database Size and Most Rows/Records. As part of the rigorous survey process, respondents must have a validated database size that meets the survey's requirements. Winter surveyed Oracle customers from 20 countries on five continents, in industries from telecommunications and government, to healthcare and banking. In all, Oracle customers made up approximately 50 percent (70 of 141) of the validated Winter TopTen Program respondents.

All customer respondents were required to complete the Winter TopTen Program survey and validate their entry by running the SQL Validation Script against their production system. The SQL Script Validation output must report a database size greater than one terabyte for Unix/Mainframe and greater than 500GB for Windows to be accepted by Winter Corporation. Winter Corporation defines database size as user data plus indices.

The complete results of the Winter TopTen Program are available at http://www.wintercorp.com/VLDB/2003_TopTen_Survey/TopTenWinners.asp.
