摘要 针对MOLAP服务器中多维数据的聚集操作,在传统的多路数组聚集算法的基础上,提出一种寻找最优聚集次序的计算方法。在实际计算中,应用这种方法可以方便、快捷地对以数据立方体形式存储于MOLAP服务器中的多维数据进行聚集操作。 With the method of multiway array aggregation, the article focuses on the introduction of the multi-dimension data saved in MOLAP server in form of data cube. Also, one way is suggested for finding out the optimal sequence of the multiway array aggregation in the three-dimension data cube, which is proved to be the most effective method to determine the sequence of the array aggregation characterized by its swiftness and convenience.
