Based The Soa School Management System Realization

The information system for universities is an integrated unit, and educational administration system occupies an important place. 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.SOA is a new organization form of information system architecture. SOA has brought profound impact on the developing module of modern software, as it provides services for other application programs through mechanisms such as the publishing, finding and the binding etc. of service. SOA possesses the sound features such as being loosened coupling, rough grain-size and retro-operative etc. Through the means of the design scheme adopting the SOA framework, the coupling among systems can be reduced to the maximum extent and the software reusing can be improved, therefore the remaining system can achieve a better integration to upgrade its flexibility and expandability. In the light of educational administration system, SOA make it easy to integration other system.This dissertation first studies Service-Oriented Architecture (SOA), further analyses Web application system and technology architecture based on SOA, and grasps how to design and realize Web application system based on SOA. Secondary it studies WebServie technology which can realize SOA in the nature of things. Thirdly it analyses status and problem of educational administration system for universities. It divides the educational administration system and analyses its function, further provides integration plan. Finally it focuses on a sub system (one's status as a student administration system).It analyses and designs the services of the sub system, and realizes the Web Service of inquiring information of student.Educational administration system for universities orients SOA is a new problem. Through compared with interrelated system, the dissertation adopts design idea base on SOA and uses Web Service technology to realize information system. It makes system flexibility and expandability..
