Service-oriented University Information Systems Integration

The information system for universities is an integrated unit. But each of its subsystem is highly independent and thus its data and services cannot be shared due to the limit of software developing technologies and the slow development of information system for universities. Thereby, information system integration is an important research area to the construction of the information system for universities as well as a pressing problem faced by universities.Web service is a self-description and self-contain application module, which is independent of developing platform and programming language. Based on the above advantages, service oriented architecture realizes a kind of standard, loose and coupling application architecture within systems.This paper did research on web service techniques and the service oriented architecture and put forward a service oriented integration solution---the integrated architecture combined by local central database and web service to the information system for universities The author analyzes in detail the data and transaction relation between university information systems. He also designs the corresponding web service as the interface for the integration of each system and realizes service-oriented integration in some systems. All services were implemented by means of encapsulating the components of legacy software or creating new web services, calling the needed services by modify the legacy software partly. In addition, the author not only researches and summarizes the design process of service-oriented integration, but also discusses how to transfer the ldgacy software to SOA. Finally, a detailed application Integration example of ZJNU Information System is proposed.Now, the information system integration for universities is a new and hot research area. The service oriented integration solution put forward in this paper is significant to the construction of the information system for universities. The research on service-oriented integration is not only important to the research of EAI in theory, but also is of important value in application.
