Abstract

See full text

Disclosed is a technique for maintaining statistics. A query is received. Column group generation is performed to form one or more column groups. Column group refinement is performed based on statistics data generated for a previously received query. A statistics check is automatically performed. A statistics collection command is generated to obtain statistics.
