摘要: 根据用户查询多样性的特点,提出了基于粗糙集聚类的物化视图的动态调整算法(RSCDMV)。该算法在对物化视图进行粗糙集聚类的基础上进行动态调整,这不仅满足了用户查询多样性需求,而且兼顾了维的层次关系因素。实验结果证明,随着用户查询集合的增大,查询集的动态性和多样性更加明显,因此,RSCDMV算法更具有优势。

Abstract: Because of user’s various inquires, a new algorithm, named rough set clustering-based dynamic materialized view algorithm(RSCDMV) is presented. Based on rough set clustering on materialized view, the algorithm can execute dynamic adjustment which both satisfies the variety of the queries and take the hierarchy of dimension into consideration. Experimental results show, as the queries set increase, RSCDMV will show more advantages as inquires change.

Key words: materialized view, dynamic adjustment, rough set, algorithm
