【摘要】：随着信息技术的发展和电力企业信息化建设的深入,电力企业对自身的信息化建设有了更高的要求,需要规范、灵活地实现各业务应用间的数据集成和信息共享,实现生产信息与经营管理信息融合。企业级数据模型在信息资源共享和信息融合中发挥着重要的作用。统一的全局数据模型,是企业信息化标准体系尤其是数据架构方面趋于完整的产物,对电力企业的资源整合、战略决策发挥重要的支撑作用。本文以国家电网公司数据模型设计项目为依托,对电力企业数据模型的研究与应用现状进行了深入的研究,提出了电力企业全局数据模型的概念。对数据模型的设计方法进行了研究,结合电力企业全局数据模型自身的特点,并将企业架构的理念引入全局数据模型的设计中,提出了电力企业全局数据模型的设计方法。在电力企业公共信息模型的基础上,参考了ERP系统和营销系统等数据模型的设计,形成了电力企业全局数据模型。通过UML的类图实现了对电力企业全局数据模型逻辑模型的图形化描述,同时将逻辑模型转化成物理模型,实现了电力企业全局数据模型物理上的存储。在电力企业数据中心中完成了全局数据模型的部署,提出了电力企业全局数据模型的验证方法,验证模型的完整性和通用性。通过实际的信息化项目验证了电力企业全局数据模型的实用性,为电力企业的综合分析与智能决策系统提供有效的数据支撑。
[Abstract]:With the development of information technology and the deepening of information construction of electric power enterprises, electric power enterprises have higher requirements for their own information construction, which need to be standardized and flexible to realize data integration and information sharing among various business applications. Realize the integration of production information and management information. Enterprise data model plays an important role in information resource sharing and information fusion. The unified global data model is the product of the enterprise information standard system, especially the data structure, which plays an important supporting role in the resource integration and strategic decision of the electric power enterprise. Based on the data model design project of State Grid Company, this paper makes a deep research on the research and application of power enterprise data model, and puts forward the concept of global data model of power enterprise. This paper studies the design method of the data model, combines the characteristics of the global data model of electric power enterprise, and introduces the idea of enterprise architecture into the design of the global data model, and puts forward the design method of the global data model of electric power enterprise. Based on the common information model of electric power enterprise, the global data model of electric power enterprise is formed by referring to the design of data model such as ERP system and marketing system. Through the class diagram of UML, this paper realizes the graphical description of the logic model of the global data model of the electric power enterprise, at the same time, it transforms the logic model into the physical model, and realizes the physical storage of the global data model of the electric power enterprise. The global data model is deployed in the power enterprise data center. The verification method of the global data model is proposed to verify the integrity and versatility of the model. The practicability of the global data model of electric power enterprise is verified by the actual information project, which provides effective data support for the comprehensive analysis and intelligent decision system of electric power enterprise.
