| Abstract: | 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. |
