Research And Application Of Data Warehouse In Flood Control Decision Supporting System

Flood control decision supporting system is a non-project measure that can efficiently lessen the scathe of flood disaster and reduce the damage of flood, it is become more and more important .There are many abuses in traditional decision supporting system, for example, the data is accumulated for a long time, saved in different types. So with the development of complication of user application, traditional decision supporting system has not been to adapt to the demand of user.Recently with the development of Internet technology, there is huge change in world economy and our life. Specially advanced technology of Data Warehouse and WEB have infiltrated in the development of network. With the development and maturity of Data Warehouse (DW), On-Line Analytical Processing (OLAP) and Data Mining (DM), there will bring more and more chances to the development of DSS.As for application, DW is not only a technology and production, but a kind of project. The building of DW is a process of decision-making and analysis implement. As for technology, DW is a method of storing data and managing resource on the technology of Data Base, and an efficient measure of extracting information on the technology and method of OLAP, and the path of discovering knowledge and disciplinarian on the model and arithmetic in DM and artificial intelligence. So, DW is an integrated application technology crossing with many subjects.The article narrates the development of flood control decision supporting system based on Data Warehouse and Multi-attribute Decision Making in the method of theory joined with practise.
