摘要 在联机分析的多维模型基础上 ,提出了实现预计算的一种快速算法 ,模拟计算的结果 。 On_line Analytical Processing(OLAP) applications require the computing of multiple related group_bys .This paper reports the performance and presents a fast algorithm which uses data cube for data precomputing . The efficiency of the method is testified by simulated the results.
