Design of the Data Exchange Center Based on Message and XML

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.
