%X Multidimensional data model is an important base of data warehouse and OLAP. In many real-life cases, particularly when exceptions arise, and their presence may turn the old dimension structure unsuitable for representing its real meaning. Based on this situation, this paper first gives some definitions about the dimension structure, and represents the effect brought by these exceptions with rules. Then describes the algorithm for revising the dimension structure in detail, including its idea and concrete p...
