【摘要】 为了解决电力系统内部异构数据共享和集中管理的问题,提出基于"集成数据库-中间件"的四层电力数据集成平台框架设计方案。该方案结合可扩展标记语言XML的优势定义数据交换格式,参考HSDA视图的组织形式搭建集成数据库,通过查询转换器、数据合法性验证工具以及数据转换器实现对用户请求的中间处理,最终将转换得到的XML文件提供给Web服务器,实现电力数据集成平台系统。实践证明,该方案对异构数据集成问题的解决提供了一个切实可行的模式和方法,具有较好的可扩展性和适应性。更多还原

【Abstract】 In order to solve the problem of heterogeneous data sharing and centralized management in electric power system,a design scheme of four-level power data integration platform framework based on the "integrated databases-middleware" is proposed in this paper,which defines the data exchange format with the superiority of extensible markup language(XML) technologies,builds integrated database by referring to the organizational form of HSDA view,achieves the intermediate processing requested by users through the query converter,data validation tool and data converter,provides the XML file for the Web server,and realizes the power data integration platform.The practice has proved that this scheme provides a practical model and method to solve the problem of the integration of heterogeneous data.It has strong flexibility and extensibility.更多还原
