A Method to Judge Whether a Data Request is Satisfiable in a Complex-Level-Structure Multidimensional Data Warehouse
复杂层次多维数据仓库中判断数据请求有解的一种方法

The dimensions of many data sets have a complex-level structure in current multidimensional data warehouse 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.
