摘要
空间决策支持系统作为地理信息系统与决策支持系统的结合体,兼有两者优点,并在国家信息化的发展中扮演越来越重要的角色。其信息模型(即空间数据仓库的信息模型)的优劣直接影响到空间决策支持系统的成败。从支持一般决策过程的角度出发,提出了一种通用的空间决策支持系统信息模型,即实体—关系—问题模型,最后给出了基于实体—关系—问题模型的空间数据仓库构建方法。
Spatial decision support system is the combination of geographical information system and decision support system, so it has the advantages of there two. It plays an important role in the development of national informationalization. Its information model, that is the information model of spatial data warehouse, is the key to the success of implementation of spatial decision support system. This paper proposes an universal, general-decision-oriented information model, entities-relations-problems, for spatial decision support system. At the end of the paper, the construction method of spatial data warehouse based on entities-relations-problems information model is discussed.
