The Winter Corp. survey, unveiled last month and detailed this week, identifies the world's largest and most heavily used databases.
The Winter Corp. has identified some emerging database trends in its Winter TopTen Program study.
The results of the study, unveiled last month and detailed by Winter this week, identify the worlds largest and most heavily used databases.
Measuring actual database sizemeaning the total disk used for user tables, indices, summaries and aggregatesand not total storage, the TopTen Program featured 141 qualified and validated surveys representing 23 countries spanning all major DBMS, server and storage vendor products, noted officials from Waltham, Mass.-based The Winter Corporation.
The study distributed awards based upon 20 different categories focusing on online transaction processing (OLTP) and decision support systems (DSS). Metrics used to determine winners included database size; normalized data volume; number of rows, records, and objects; and peak workload activity. For peak load activity, the study examined the highest number of transactions per second for OLTP, while for DSS the highest number of concurrent, in-flight queries was analyzed.
Among the more notable findings, Microsoft Windows growth increased from less than 20 percent to over 40 percent in OLTP within operating system (OS) usage from 2001-2003, narrowing the gap the Unix and IBM z/OS mainframes hold as processor of choice.
