摘　　要：基于基库的多实化视图维护将基库集作为多个实化视图的辅助视图集保存在集成端。当信息源发生变化时,基库随着更新,同时触发多实化视图的更新与维护。在保存基库的情况下,多实化视图的维护无需访问信息源就可完成,是多实化视图的自维护方式。The maintenance of multiple materialized view is a self-maintenance algorithm based on radical database.The radical database collection which are considered as auxiliary views of multiple materialized view are saved on the integration point.The radical database will update when the information source change and can incite the materialized view to update and maintain.The maintenance of multiple materialized views can not depend on the information source if the radical database is saved.

关 键 词：基库 相容性 辅助视图 自维护
