1) 2-Phases Materialized View Selection(2-PMVS)
两阶段物化视图选择算法
1.
To address the problem that the current materialized view selection methods couldn\'t solve random OLAP query efficiently,this paper proposed a 2-Phases Materialized View Selection(2-PMVS) algorithm which combined static materialized view selection algorithm with dynamic materialized view selection algorithm.
针对现有物化视图选择算法无法很好解决OLAP随机查询的问题,提出了一种新型的两阶段物化视图选择算法(2-PMVS),将传统的静态选择算法与动态选择算法相结合,使其可以动态矫正用户随机查询与预估查询之间的偏差。
