Li Qian · Huazhong Normal University Journal of Postgraduates · 2009
From the aspect of the relevance of objects,the hierarchical feature of Multi-dimensional Sets was analyzed.From the simple relationship to the complex relationship,topology was used to describe the hierarchical feature.While the example of book lending was used to display the relationship of the data from Multi-dimensional Sets,strengths and weaknesses of each methods from topology were also analyzed and transition rules for these methods which were used to describe the data relationship from low levels to high levels were provided.Then the representation methods of Multi-dimensional Sets in the relational database and object-oriented database were respectively interpreted.
