Research And Design Of Hierarchical Systems Integration Based On Web Services

With the development of social information, integration schema of hierarchical systems Integration based on Web Services has becoming the leading EAI field. Traditional Integration methods usually integrate applications from peer to peer. It has many deficiencies, such as poor ability of integration, poor extensibility, poor interoperability and high cost in integration. But Web Services has the predominant features of interoperability, encapsulation, low cost, loose coupling structure, normal protocol and high integration. The characters of Web Services will fetch up to the integration about enterprise in and out application. It needn't to install a special agreement on the server and client, which only need to support HTTP protocol and data format (XML) for mutual communication, use XML language and SOAP protocol to realize the integrations of hierarchical systems Method.This paper is based on the power system of ShaoGuan smeltery. The main purpose is data exchanging and sharing in hierarchical systems. On the basis of research of traditional technology and the project we are working on, considering the requirement and efficiency of the system, a solution based on WS-EAI is proposed and design it based on C# language. An advanced data warehouse is adopted in solution of data sharing in three remote control system and Honeywell system. This system can support data service to client and good data interface to senior integrated system. The portal site is design to integrate all systems data. Web service is adopted in solution of data sharing in three remote control system and Honeywell system. Through by Web services, a uniform access interface to databases is provided to mediate which screened the heterogeneity of database. So hierarchical databases can be accessed in the same way, and data can be used in senior layer in the same way, too. This system reduced the code lines for programmers, data sharing in three remote control system in wider range is provided. To improve the security of the model, we research for the security of SOAP message exchanging with the WS Security framework, we introduce how to realize the security of SOAP message exchanging in the framework of WS Security. At the meantime, the data can be distributed to web, data cover area is improved. Practices prove the solution can better solute the"information isolated islands".
