摘要
提出了建立数据交换中心来统一协调系统彼此之间的数据交互。设计中采用了经过加密的 XML文档作为数据交换的媒体 ,并建立具有行业特色的 XML方言 ;数据交换中心作为独立的应用服务组件存在于企业的信息系统中 ,而不依赖于任何一个独立的信息系统 ,所有的数据都经由数据的拥有者和请求者进行处理。数据交换的过程采用基于消息的异步方式 ,数据交换中心对消息进行全程管理 ,保证消息的接收顺序及数据的正确性 .对外提供消息控制 API和数据转换协议定制工具 ,使得任何系统只要通过数据转换协议定制工具往数据交换中心中添加数据转换协议 。
Power trade has many relative independent business applications of different system structure,so the data exchange is very difficult.To solve the problem,this article focuses on setting up the data exchange center(DEC)to coordinate the data exchange between different applications.According to the design of the data exchange center,the encrypted XML documents is used as bridge of data exchange which is constructed by the unique XML language with power business style.The data exchange center is just one independent service component applied to the power information system,which doesn't depend on any independent information system,all data processing must be initialed by the owner and requester of the data.The process of data exchange is based on the asynchronous message that is fully controlled by data exchange center,this way ensures the sequence and accuracy of the message.Data exchange center also offers the API and custom-made tool for message control and data exchange protocol,which means any applications could add data exchange protocol into the data exchange center by the tool offered by the DEC then message-control-API can be used for data exchange with DEC.
