摘要
传统数据仓库及OLAP应用侧重对历史数据的分析。为了满足实时分析的要求,本文提出了一种实时数据仓库的分区结构。在分析了传统OLAP设计在实时性方面的缺陷后,我们提出了基于分区结构的实时OLAP的设计,使OLAP分析能够达到实时或准实时的要求。
Traditional data warehouses and OLAP applications emphasize particularly on the historic data analysis. This paper introduces a partition structure for real-time data warehousing, meeting the needs for real-time analysis. After analyzing the shortness of real-time for traditional OLAP strategy, we introduce a real-time OLAP strategy towards our partition structure.
