Unified Network Teaching Platform, SOA Architectural Research

With the computer and network technology, through online teaching system to achieve extra-curricular student learning and interaction between teachers and students has become a very good teaching aid. Unified network teaching platform system for students to build self-learning and communication environment conducive to teacher-centered teaching model to under the guidance of the teacher to student-centered teaching model. Therefore, many colleges and universities have developed their own online teaching system in order to achieve network-based online-assisted teaching. This new means of supporting the teaching curriculum for further improving the quality of teaching has a positive meaning.However, if the use of current software development technology development of this system will make the network teaching platform is just an isolated system(Information islands), can not reuse the original teaching and academic systems software modules and share data. Can not be with the school to integrate other applications. In order to make the system more scalable, more powerful and able to adapt to the future of software development, this system uses the relatively cutting-edge technologies: SOA.SOA (Service-Oriented Architecture: Service-oriented architecture) is a service-oriented architecture model, which can be on demand through the network of loosely coupled coarse-grained application components distributed deployment, composition and use of. In the SOA architecture model is based on the service layer can be directly invoked by applications in order to effectively control the traditional software development model will be a revolutionary change. As a new software architecture, SOA has an unparalleled advantage in line with the development of on-demand computing trend, especially for enterprise-class application development.With the further development of the Internet, SOA applications will become more common and was accepted, becoming the object-oriented, component-oriented software architecture after the new model and design approach.
