摘要
采用基于数据仓库的决策支持系统(DSS)的体系结构,综合运用数据仓库、联机分析处理(OLAP)、数据挖掘、信息智能推拉等多种信息处理技术,利用数据仓库技术集成各领域异构数据库系统,通过对大量的相关信息进行提取、清理、转换,并按决策主题的需要对数据重新组织及统计、分析和处理,以多种形式灵活地生成各种应急方案、多维数据分析报表以及各种可以旋转的三维图形,形成综合的、面向分析的决策支持操作平台,具有可操作性的、能辅助决策者进行应急处理决策的支持系统。
The system structure is used to design intelligent DSS of city defending and salvaging for disaster. Also the information tech- nologies of data warehousing, OLAP, data mining, intelligent information pushing and drawing are used. Using data warehousing technology makes integrity of heterogeneous databases. According to the operation requirement and characteristic, a lot of correlative information are picked up, cleaned up and transferred. According to the requirement of decision theme, data is organized, computed, analyzed and disposed. Atlast all projects meeting an emergency, multi-dimension dataanalysisreport forms and three-dimension graphs are created. The decision supporting operation plat is formed. The intelligent DSS is developed for city defending and salvaging for disaster.
