  • Missing index analysis and index useage statistics
    Patent number: 7769744
    Abstract: A method of accumulating and aggregating statistics concerning the use of database table indexes includes using a plurality of counters to register index use. The plurality of counters allow multiple instances of index usage to be recorded simultaneously. A missing index may be detected using an optimal index in a query plan. The optimal index is compared against the available indexes to determine if an index is missing. Statistics may be gathered against the used and missing indexes.
