摘要: 数据仓库通常以离线的方式进行刷新,这样就不能向用户提供连续的查询服务。文章提出了一种适合数据仑库联机维护的算法─STNL算法,它消除了2VNL、MVNL等联机维护算法需要对元组暂时锁定的缺点,并且更容易实现。

关键词: 数据仓库, 联机维护, 2VNL, MVNL

Abstract: Data warehouse maintenance algorithms usually work off-line, making the warehouse unavailable to users. In this paper, we present an online warehouse update algorithm-STNL STNL eliminates the limitation of other online warehouse update algorithm that a latch has to be held on the tuple, when the tuple is modified by the maintenance transaction. And it is more easy to implement STNL than to others.
