摘    要:借鉴传统的基于基表变化的数据仓库维护方法Strobe,提出一种基于源视图增量的在线实化视图自维护方法,使实化视图的状态保持与底层数据源的一致性。这种方法不仅保持数据仓库数据的一致性,而且还能够加快实化视图维护的速度,减少底层信息源与数据仓库之间的网络通信负担。

关 键 词:源视图  视图自维护  数据仓库

Abstract:View maintenance is an important field in the research of dataware house. This paper got idea from the strobe algorithm and provided an online view self-maintenance method based on source view's increment to keep the materialized view consistent with the data sources. This method does not require querying back to data source; it can accelerate view maintenance and decrease the burden of communication between dataware house and data sources.
Keywords:source view  view self-maintenance  data warehouse
