摘要 讨论基于主存联机分析处理(OLAP)环境下的What-if分析,规范基于OLAP环境下What-if分析的表现形式及原操作,在此基础上,提出一种基于用户查询结果动态创建HCube或VCube的算法,以支持多版本的What-if分析,介绍系统的体系结构,实现一个原型系统。 The What-if analysis in Main Memory On Line Analytical Processing(MMOLAP) environments is discussed. The expression form and original operating of what-if analysis in OLAP are formulated. On this basis, an algorithm for dynamically creating HCube or VCube with users query is proposed, Which supports multi-edition What-if analysis. The system structure is introduced, and the a type ofproto-system is implemented.
