ABSTRACT:
Database indexes include multiple fields that are used to track how the components of the index are used. An index component monitoring mechanism tracks how the components of the index are used, and updates fields in the index accordingly. Such component-level statistics allow a query optimizer to make more intelligent decisions regarding when to build a new index and when to discard an index, and also provide information regarding which queries are using the index, the maintenance cost of the index, and the selectivity of the index when used to process a query.
