The Concept of Attribute Dimension and Corresponding Operations
属性维概念及其操作的研究

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 multidimensional data modeling in many real-world applications, the traditional multidimensional structure is extended and a group of operations are given to formulate corresponding multidimensional queries.
