The results of Winter Corp.'s 2003 TopTen Program indicate that the scalability of online transaction processing (OLTP) and decision-support databases has increased dramatically in the last two years. Winter records an almost 100 percent expansion in the size of the largest transaction-processing database, from 10.5 TB to 18.3 TB, while 2003's biggest decision-support system (DSS), at 29.2 TB, is about 300 percent larger than the leading DSS of 2001. Significant growth in row count for all OLTP and DSS database platforms is also documented: The average row count in Unix DSS databases experienced a six-fold increase, average row count for Windows OLTP systems expanded 14 times, and Windows DSS systems' average row count rose from 1,176 two years ago to 11,112. There was a 44 percent rise in the number of concurrent in-flight queries processed by the average DSS database between 2001 and 2003, while transaction-processing workloads experienced 54 percent growth. Aggregate storage was upgraded from 632 TB in 2001 to nearly 2 petabytes in 2003 ...
