> 中文摘要: 提出了一种版本控制集合刷新算法(VSRA).它采用增量维护、版本控制和批处理机制保证数据仓库的联机维护和数据一致性.VSRA不仅减少了数据库和数据仓库之间的通信流量,而且提高了实体化视图的刷新效率.用户可以随时使用VSRA进行联机分析处理,并能得到正确的结果.
Abstract:In this paper, a Version-control Set Refreshing Algorithm (VSRA) is proposed, which uses incremental maintenance, version-control and batch processing mechanism to guarantee on-line maintenance and data consistency. VSRA not only reduces communication between database and data warehouse, but also promotes the refreshing efficiency of materialized views. Users can perform on-line analytical process at any time and get correct results with VSRA.
