Online self-maintenance of materialized view based on source view increment
基于源视图增量的在线实化视图自维护

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.
