Abstract: 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 of proto-system is implemented.

Key words: Main Memory On Line Analytical Processing(MMOLAP), What-if analysis, view
