The Research And Development Of "Korean Basic Course" Network Teaching System

This paper which named "the research and development on the network teaching system of Korean Language Basis", is a part of network teaching system in Jilin Radio and Television University. It consists of the project developing background, the design of development objectives and the model of system demand. It also analysis the relevant technology in developing process and describes the designs of the database, the logical structure of systems and physical structure, different functional models and the key technology and algorithms on each model.In the first chapter, the paper describes the background of project development. The author took part in the work of research and development on the network teaching system of "Korean Language Basis".In the second chapter, the paper sets the project goals, implementation plan and design features, and describes the demand model of system by using UML use case diagram. It introduces the relevant technology, including ASP technology, ACCESS database, ADO technology, structured query language SQL, JavaScript language and UML technology.In the third chapter, the paper describes the database structure of the systems, including E-R model and the logical structure of each data. Considering the system requirements, it also designs the logical structure of the system based on the data structure, which is called "B/S three-layer structure". The structure consists of three layers, including performance layer, business logic layer and data service layer. The paper designs a system of the physical structure and divides the system into six subsystems by using structural design tools, and designs the system of functional modules and constitution pages to ensure good performance and improve the response rate and security s of system.In the fourth chapter, the paper describes some key technology of the subsystem, including the Flash and HTML form technology on implementation of the online study of the subsystem, the key codes about getting and operating the "knowledge tree" on subsystem of knowledge points, the session management techniques and LyfUpload assemblies uploaded to the process on subsystem of exams bank management and the key codes which can delete the same point and the judge the intersection between the two series on the subsystem of the exam organization management.In the fifth chapter, the author summarizes the main results of the network teaching system on Korean language basis which was put into use.The further work of this system includes:1) Considering the customer's demands, we should improve the operation on "knowledge tree" by using Jquery, ExtJS and Ajax technology.2) We should regular the rights of teacher users, and allowed the system administrators to assign different operating rights to different teachers according to different needs.3) We should upgrade the system by using JSP and ASP.NET technology in order to enhance the system character of maintainability and scalability.
