Zhao Yuyua · Jisuanji gongcheng · 2000
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.
