摘　　要：文章定义了满足约束条件的多维立方体模型。通过定义基本立方使常规的上卷和下钻操作合二为一。该模型展现了维度的层次关系,支持不均衡及非严格的层次结构。实现了度量的多种聚合操作及度量和维度的相互转换。以一种更简明的方式展现了针对立方体的基本操作。The article designed Multidimensional Data Model that satisfied with restricting conditions. The article designed basic Multidimensional Data Model that made rolling up operation and drilling down operation to unite so as to be continuous. This model is able to represent hierarchical relationships within a dimension and support unbalanced hierarchy, relaxed hierarch. The model implemented some aggregation operation of measure and mutual conversion from dimension to measure. The article described the operation on the Multidimensional Data Mode through simply way.

关 键 词：多维立方体 基本立方体 维度 度量
