Winter Corp has published a white paper titled "Spotlight on Oracle - Key Findings from the 2005 WinterCorp Top Ten Program", which measured the world's largest databases. The report can be downloaded from Oracle.com here.
Some of the highlights of the paper are:
- The largest data warehouse runs on Oracle
- The largest scientific data warehouse runs on Oracle
- It is unlikely that any database vendor's product is as omnipresent as Oracle in the VLDB arena
- In both the 2003 and 2005 TopTen surveys, all ten databases in the UNIX OLTP workload category run Oracle
- Oracle is the only database with a showing in the survey, and a strong one at that, across UnIX, Windows, and Linux platforms
- Nine of the ten largest UNIX OLTP systems run Oracle
