Design And Implementation Of Support Platform For Complex System Based On Web Service

Along with the rapid development of the Internet,a wide range of software system came into being. Deficiencies of development model of traditional software,such as long development cycle,poor stability,structural disorder and difficult to maintain,are exposed.Due to the continuous application of technology of object-oriented and distributed, technology of software reuse has gained a rapid development. Methods of component-based multiplexing can not only solve problems exposed in the traditional software development,but also lay a certain foundation for software reconstruction later. Technologies of traditional component model,such as CORBA and DCOM,can communicate only in the LAN for inability to penetrate the firewall. WebService in the context of service orientation has unique advantages of cross-platform and cross-laguage, which is based on HTTP protocol and uses XML of platform-independent format as a data transmission carrier.In this paper, a generic support platform of web service with the distributed technology is developed for the purpose of reusable components and scalable system.The platform itself contains a set of service-oriented design specifications,such as interfaces, parameters, exceptions, etc; Meanwhile we also design some generic and basic module assembly based on the specifications of platform,such as database service, rights management service and single sign-on service. It's important to note that paper focused on analyzing the universal design of communication protocols and basic modular on the platform and suggested that service or application following the design principles of the platform has a clear architectural style and good coding standards,which both to ensure the quality of the software but also significantly improve the maintainability and scalability of the system.Finally, practical effect of this support platform is analyzed. Through analysis of the process of development and test results of the system based on the support platform,it is proved that the platform has highly reusable characteristic and practical value.
