In a recent press release, Winter Corporation, a leading center of expertise in database scalability, announced the results of the 2005 Winter TopTen Program, a survey of the world’s largest and most heavily used databases. Here are some interesting facts:
- Yahoo! has the largest database. The 100.4 TB Unix-based data warehouse infrastructure runs the Oracle database.
- The largest OLTP system is Land Registry for England and Wales. The 23.1 TB system employs IBM DB2 Universal database.
- UPS shipping system achieved a peak workload of 1.1 billion SQL statements per hour. UPS uses IBM DB2 Universal Database.
- The largest Windows data warehouse is 19.5 TB.
- The number of records topped 2.8 trillion.
- Linux appears as a platform for large databases.
The survey results show the dominance of Linux/Unix and Oracle for large databases.
Speaking of large databases, does anyone know what database Google uses? I suspect it should be more than 100 TB.
Update: Matt sent me the following interesting document: The Google File System.
