Abstract
A technique for refreshing materialized views in a database is disclosed. The detail table is partitioned, and changes made to the detail table are tracked with information stored, for example. Only sections in the materialized view which correspond to the partitions which include modifications made to the detail table are refreshed, thus avoiding the need of a complete refresh to overcome staleness.
