A system and method for directing a data processing system to
incrementally process a base table and a materialized view, wherein the
materialized view is associated with the base table, and both are stored
in the system, is disclosed. The method includes setting integrity of the
base table having an identifier identifying data newly load appended to
the base table, and placing the identifier into a location if the
location does not contain any other identifier identifying any other data
newly load appended to the base table. In a preferred embodiment, the
materialized view is incrementally refreshed using the identifier.
