摘要
论文研究了ROLAP中的实化视图的选择与调整问题,推广了现有的实化视图选择方法,并证明了这个推广的有效性。在此基础上,首次提出了一种局部调整实化视图集的方法———淘汰替换算法。最后,介绍了这些方法的一个应用实例。
In this paper,we study the problem of materialized views selection and adjustment in ROLAP,extending the existing method of views selection and proving the validity of extension.Then we present a method for partially adjusting materialized views set,which is called elimination-replacement algorithm.Finally,we introduce an application instance of these methods.
