基于数据仓库技术的决策支持系统

Decision Support System Based on Data Warehouse Technology

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。
