  • System and method for asynchronous view maintenance
    Patent number: 6546402
    Abstract: A method and system for refreshing materialized join views includes asynchronously evaluating changes to the base tables, i.e., evaluating changes for an intended time tintended at an evaluation time teval that is later than the intended time. Changes made to the base table between the intended time tintended and evaluation time teval are recursively compensated for. The results of the evaluating and compensating are then applied to the materialized view to refresh the view.
