METHOD AND SYSTEM FOR IMPROVING RESPONSE TIME OF A QUERY FOR A PARTITIONED DATABASE OBJECT

摘要

A kind of method and mechanism, to improve the inquiry of response time execution for partitioned data base object. Only accessed during subset or partial-partition it is each by subregion, wherein the partial-partition processing only retrieved, result can return to inquiry immediately. Only it is to be processed repeatedly to allow given transmitting for each subregion in the subregion of processing a subset, rather than requiring the first subregion is entirely processing, is then handling the second subregion. In one approach, which includes that the inquiry of sentence command result collection is directed to partitioned data base object, and it includes local indexes.
