【摘要】 针对现阶段电力企业信息化存在的问题,提出以企业级数据仓库为数据中心,并描述了电力企业基于数据仓库策略的信息系统模型的总体设计;为解决异构系统数据提取困难的问题,设计出一种基于CIM/XML的数据登台方案;为电力企业数据仓库维度模型的设计给出了具体解决方案和应用实例分析。更多还原

【Abstract】 Based on the research on the problems existing in power information construction, an enterprise-wide data warehouse is proposed to acts as the data center.Firstly,this paper describes a possible architecture of the future power utility information system based on the data warehousing strategies.Secondly,to tackle the problem of extracting the data from different systems,a data staging approach based on CIM/XML is designed.Finally,the concrete scheme of the dimensional model design in power utility is proposed,and an application instance is illustrated.更多还原
