摘　　要：随着电力企业信息化的不断发展,信息建设中存在的IT系统各自为政,主数据冗余,缺乏统一标准,一致性难以保证的问题日益突出。为满足信息系统"一体化"的需要,合理规划企业数据资源,构建企业级数据模型成为一种必然的选择。本文详细介绍电力企业概念数据模型建设思路、主题域、实体、关联关系设计原则和规范。目的是通过面向对象数据模型的优势,从数据规划层次考虑整合业务系统需求,保证数据唯一性,降低集中集成开发的复杂度。With the continuous information development of power enterprise,the IT system builds applications by their own ways,the data are redundancy,resources lack the unified standards,compatibility difficulties are outstanding gradually.In order to satisfy the information system ＂the centralism integration＂ and plan the business data resources reasonably,the construction of enterprise data model becomes one kind of inevitable choice.This article introduces the construction idea of conception data model,the subject territory design,the entity design,the incidence relation design and the standard in the power enterprise.The goal is to guarantee the data uniqueness,reduce complexity of exploitation in the centralism integration,through the object-oriented data model superiority,integrating business system demand from the data plan level consideration.
