视图匹配算法的研究与实现

Study of a view matching algorithm and its implementation

研究了一种可伸缩的SPJG视图匹配实用算法 ,介绍了DM3上实化视图的定义和SPJG视图匹配算法的基本思想 ,并且将SPJG视图在DM3上具体实现 .

Using materialized views to answer queries is an important technique to speed up query response in data warehouse systems. In this paper, a practical and scalable algorithm for SPJG view matching and its detailed implementations on our native database management system DM3 were studied.
