【摘要】 数据仓库技术的产生是由于决策支持系统发展的需要,是体系结构设计的核心。数据仓库必需设计成可扩展的体系结构,从而满足不断增长的数据和用户的需求。本文通过对数据仓库平台布纹和表格分割进行研究和分析,使得当大量异构数据涌入数据仓库平台中时系统性能不会下降,很好地满足决策支持。更多还原

【Abstract】 Data warehouse is the kernel of architecture design,and came into being with the requirements of decision support system.To satisfy the requirements of increasing data and users,data warehouse must be designed with scalable architecture.In this paper,data allocation and table division are researched and analysed.A good effect on system performance is obtained when a great deal of heterogeneous data swarming into data warehouse,and meets the needs of decision support better.更多还原
