摘要: A method, apparatus, and article of manufacture for computer-implemented exploitation of database indexes. A statement is executed in a database stored on a data storage device connected to a computer. The database contains data. A model based on pattern matching for a user-defined predicate and selection of an index exploitation rule based on a matched user-defined predicate is provided to be used for exploiting an index to retrieve data from the database.
