Abstract: Based on the sufficient study and analysis of dam safety assessment decision support system, and with the advanced development of computer science and technology, two key points,management information system and decision support system are reviewed. In dam safety assessment decision support system, non-structured internet database system is used. With the comparison between the new dam safety assessment system and the conditional one, a new program of dam safety assessment decision support system based on data warehouse technology is presented.

摘要： 本文在充分研究和分析大坝安全评价决策支持系统的基础上，结合计算机科学与技术的发展，详细论述了大坝安全评价决策支持系统开发的两个关键点，即管理信息系统与决策支持系统。在大坝安全评价决策支持系统中，选择了非结构化的Internet数据库技术；在此基础上，与传统的大坝安全辅助决策系统对比，提出了基于数据仓库技术的大坝安全评价决策支持系统的解决方案。
