GENERATING FILTERED DATA SETS FOR EFFICIENT QUERY EXECUTION

Abstract:

A system filters a data set for the efficient execution of queries by removing at least some irrelevant records to generate a reduced data set. The records are determined to be irrelevant based on the values of the records for the particular attribute(s) corresponding to the filtering operation. The system filters out records within a data set that do not include any of the values defined for the particular attribute by a set of queries that are to be executed on the filtered set of records.
