The Study Of The Teaching Management System Based On Soa And Saas And Design

In recent years, along with the development of information technology, the informatization of educational field of our country has achieved fruitful results. However, there is still a series of problems during the process of educational information for being lack of a unified management and planning. To the development of teachers management system as an example, all schools act as their own will during the process of system development. Based on different platforms and different technologies they developed the teachers management system which suited to theirs. That leads to dozens of teachers management system in the real world. There is a convergence among the teachers management systems in the function. According to the statistics, there is a convergence among80%of the main teachers management system in function. This caused such a phenomenon that80%of the work is in duplication of development during the developing process of teachers management system. The100%input of resources, only about20%of the investment return, that is just waste of resources. Now we need to seek a kind of software development method, to solve the problem of duplication development existing in the teachers management system.SOA (Service Oriented Architecture) is a kind of service oriented architecture. Based on SOA system, it is service oriented. The service is reusable, and can be assembled into a business process and ultimately realize a business function. Services can be provided from outside for the user invokes the standard interface for Web Service.SaaS (Software as a service) is a recently developed operation mode which can through the network to provide software service. It takes the application software as a service. The application software is deployed in their server by the owner of the software. According to their actual needs, the users can rent the necessary software services from the software owner through the network. Service providers can also realize service unified management, maintenance and upgrade through the SaaS mode. So as to avoid the inconvenience of traditional mode that someone is need to maintain software upgrade.Through the in-depth study of the SOA software architecture, this article analysed the current advanced SOA core technology. In which, the SCA implements the development of service component; the SDO is used to build a unified messaging data model. At the same time, it deeply studied the Web Service based on SOA system, and bound the SCA component development with Web Service. It designed teachers management basic function service which can be called through the internet. Through the duplication of these services, the duplication of development during the developing process of teachers management system can be solve. And the teachers management software business model which based on SOA and SaaS is implemented in Philosophy.
