The research and design of the network teaching platform based on multi-layer architecture

Research on the Web Service technology is carried out according to the practical system acquirement, the priority and advantage of the Web Service technology is explained. Based on the deep analysis of the architecture and the implementing theory of the Web Service technology, the network teaching platform based on multi-tier architecture is designed, in which Web Service is used to the design of this system. The presentation layer, business logic layer, data persistence layer are more effectively separated, and we have adopted the service-agent mode, which enhanced the stability, security and the flexibility, as well as the reusability of the code, and the development efficient etc. of the system.
