This paper studies of B/S mode application model and provide relative function design modules for online English Multimedia teaching system. The system is based on J2EE technology. The development of Web layer, business logic layer and data layer for function module are discussed in detail. By the research on system structure, processing model, structured analysis techniques and object-oriented analysis we obtain the main demand and non-functional demand of system. Then according system design rules, we describe the main modules by system foreground and background data management system, to offer a detailed structure designed scheme. The system tests show that the system in this paper can well adapt the actual characteristics of online open English teaching, and meet the demand for teaching assistant functions.
