In order to realize the information management of college English learning, improve the management efficiency of college English teaching, and reform the traditional applied teaching mode, this paper proposed to design a college English online learning system, which uses Browser/Server (B/S) as the architecture, JSP technology as the programing language, and MySQL database technology as the data storage and management database. Then, this paper fully analyzed the requirements of network English teaching and management and the demands of system users. On this basis, functional module, database design and overall system architecture were designed, with the relevant interface displayed. The design and implementation of the system can improve the efficiency and quality of English teaching and effectively advance the teaching level of college English, which can be applied into extensive fields.
