摘　　要：The dimensions of many data sets have a complex-level structure in current multidimensional data ware-house models. But the data warehouse can't implement all the data at every node of these dimension levels because of the large amount of data,so it's necessary to judge whether a data request is satisfiable in a complex-level-structure multidimensional data warehouse. In this paper,a method is presented to solve this problem. The characteristics of prime number are applied.The dimensions of many data sets have a complex-level structure in current multidimensional data warehouse models.
