摘　　要：Dimension member attribute is used to describe the property of dimension members. It is not fully understood and well defined in OLAP research area. This paper focuses on a special kind of dimension member attributes, which can be used as dimensions by themselves. We call them attribute dimensions. In order to facilitate this kind of necessity of muhidimensional data modeling in many real-world applications, the traditional muhidunensional structure is extended and a group of operations are given to formulate corresponding multidimensional queries.Dimension member attribute is used to describe the property of dimension members.
