摘要： 在保存多维数据集数据的过程中,引入了层次式B+树的概念,提出了用层次聚集CUBE的方法,不仅可以利用所保存的层次信息优化OLAP聚集查询操作,而且使得多维数据集模式更新操作成为可能。同时,层次聚集CUBE也可以看作是实视图的物化,可以根据某种策略进行动态调整。

Abstract: This article provides the concept of hierarchical B+ tree in saving multi-dimensional database. By this concept, it introduces the hierarchical cluster CUBE (HCDC) method which optimizes the efficiency of querying and updating with the hierarchical information, and enables the manipulation of updating of multi-dimension data’s schema. Furthermore, the hierarchical cluster CUBE can be regarded as materialize of real view which can be dynamically adjusted by certain strategy.
