World's Largest Commercial Database Runs Oracle

June 16, 2004

In a 2003 Winter Corporation Top Ten Survey, which offers independent third-party validation, Oracle is named the leading database for transaction processing and decision support in real-world customer environments;

*  The world's largest commercial data warehouse runs Oracle, with 30 terabytes of data.

*  The world's largest transaction processing database on Unix, the U.S. Patent and Trademark Office's Patent Electronic Processing System, runs Oracle with more than 5 terabytes of data.

*  Oracle customers run the world's top 10 OLTP databases on Unix (OLTP Sites by Database Size, and by Most Rows/Records); Oracle Collaboration Suite Email Server handles more than 2.2 terabytes of data.

*  Oracle customers run 3 of the top 10 OLTP databases on Windows; the largest manages   3.2 terabytes of data (OLTP Sites by Database Size).   (Source: Winter Corporation,

Winter Corporation describes the judging process,

"The 2003 Winter Corporation Top Ten 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 meet the survey's requirements.

Winter surveyed Oracle customers from 20 countries on 5 continents, in industries from telecommunications and government, to healthcare and banking; Oracle customers comprised 50% of the validated Top Ten Survey respondents.

All customer respondents were required to complete the Winter Corporation Top Ten 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."
