摘要
20世纪90年代以来,数据仓库(Data Warehouse,DW)技术逐步被人们所认识、认可、应用。决策支持系统(Decision Support System,DSS)因数据仓库技术的介入,克服了众多缺陷,获得了长足发展。结合了DW技术的DSS系统在众多行业中得到应用,然而这些应用往往是一次性的,即使类似的企业,实施也截然不同,造成了大量重复性的探索。有没有共同的规律可寻呢?回答是肯定的。本文从传统DSS系统的缺陷出发,论述了DW技术对DSS的支持,试图从一般意义上构建基于数据仓库技术的决策支持系统。
Since the 1990s,the data warehouse technology has gradually been recognized,acknowledged,and applied by people.Decision support system,combined with data warehouse technology, have achieved great development since then.Athough decision support system has applied in many industry system,but it's often a onetime-project.Even in similar enterprises,the implementation and different.Are there any common rules can be found?The answer is YES.Started from the defects of the traditional decision support system,this article discussed the support of data warehouse technology to decision support system.The author trved to build a decision sutmort system based based on data warehouse technology
