水文数据在线分析与知识发现系统模型研究

System model for online analytical processing and data mining of hydrological data

数据的在线分析与知识发现是开发信息资源的高级形式 .为了挖掘关于水的运动变化规律和对环境的作用的知识 ,作者提出了水文数据的在线分析与知识发现系统模型 .文章对模型采用的在线分析处理与数据挖掘相结合的分层次结构进行了详细阐述 ,并重点介绍了模型中的关键技术应用 .

Both online analytical processing(OLAP)and knowledge discovery in database(KDD)are advanced modes of information resources exploitation.A system model for online analytical processing and data mining(DM)of hydrological data is proposed to acquire the knowledge of the laws of water movement and its effect on environment.The layered construction of the combination of OLAP and DM is presented in detail and the key technology to be applied in establishing the model is introduced.
