Research And Design Of University Enroll System Based On SOA

Rapidly changing their business models, IT technology and IT architecture continues to evolve, making the enterprise IT departments are struggling on how to resolve the challenges of IT systems posed by new demands of the business, and protect the existing investments to get high return while have low risk, and how to implement it to a technology strategic and model that can really align to business.SOA is Service-Oriented Architecture. Enterprises can improve the bussiness agility, decrease the cost of IT development and improve the efficiency by integrating the internal resources and sharing each other' s resources through SOA system. So, SOA is a mainstream solution now.In this paper, made a system learning of the related theory of SOA from many aspects, got a profound understanding of the service-oriented design. Studied the SOA programming triangle SCA + SDO + BEPL which is a new advanced programming model currenttly, and made a further study of the three components from the aspects of thetechnical advace and specifically regulate. Then, researched on the theory and system structure of using SOA for integration based on Web Services,compared SOA with Web Services and elaborated the relationship and difference between them. By research on SCA which is the programming model of SOA,combining the advantages of SCA and Web Services, designed a system architecture based on the combination of SCA and Web Services. The architecture can not only solve the problem of service combination and assemblage, but also solve the problem of data programming in SOA system design, while also simplified the exploring process of using SOA to construct the application system.Futher more, it enhances the system' s portability, reusability, flexibility. Finally in accordance with system architecture design, combined with SOA programming model, design the system from the layers of the data modeling, service development, business process choreography.The university enroll system based on SOA can construct a new system while make the most of the university' s existent system resources, it solve the problem that the current university enroll system can' t adapt the need of frequently alter or reconfigure of the operations, and it discards information island problem. The new system is loose-copule, resuable, expanded, and can rebuild the workflow fast according to the change of the work need.
