The Design And Implementation Of Excellent Course Management System

With the accelerating pace of informatization, the network, digital and intelligent asrepresentative of modern information technology is changing people’s work, learning and life, italso brought new development space to the career of education. Construction of excellentcourses in Colleges and universities is a system engineering which deepening teaching reformand improve the teaching quality. Students can experience the advanced teaching method,learning content is rich during school, and teachers can obtain a large number of advancedteaching information, promote the interactive communication with students, so as to improve thecomprehensive quality and ability of teachers and students. Therefore, the design andimplementation of an excellent course management system is very necessary.The excellent course management system adopts the method of software engineering toanalyze and design, this paper mainly introduces the system requirement analysis, overall design,detailed design, database design and system implementation and test. This paper describessystem function demand with the method of use case analysis, through the use case diagram, theactivity diagram and the use cases description table describes the detailed function of the system;The overall design use the function structure diagram, network topology diagram and technicalarchitecture diagram to describe; In the detailed design of the system, the basic class need todesign first, then with the aid of class diagram and the timing diagram describes the detaileddesign system; The content of the excellent course has made a reasonable database modeling andanalysis and based on the3NF of database design reasonable E-R diagram; Through the systemfunction realization rendering shows the system function and briefly introduced theimplementation code for part of the system function; Through design the functional test cases todescribe the system functional testing, and complete the whole development of the excellentcourse management system. Through the use of thoughts, methods and tools of softwareengineering to carry on detailed design and analysis of the excellent course management system,which ensures the internal structure of the excellent system. The design of the excellent coursemanagement system, which compares with the general to simple web technology to design thesystem have a better logical and extensible, effectively reduces maintenance costs.The excellent course management system finally realized six main functional modules,inluding declaration form management, course management, teaching resource management, teaching effect management, discussion management and user management, which basicallymeet the demand of experimental teaching work. The paper makes the declaration form contentof the excellent course detailed decomposition, which greatly facilitates data storage, edit, queryand statistics; Using Youku professional video storage and Application Programming Interfacetechnology (API) to manage and play the video of excellent course. It solved the general systemof excellent course that using simple file storage and download way to broadcast video to causeslow play, not smooth and even crash phenomenon. The system is designed with a user-friendlyinterface and a more complete function, and has good operability, which avoids the constructionof quality courses in different repetitive work and makes every course of the joint excellentcourse system with a unified structure and user experience. At present, the implementation ofexcellent course management system has been applied. It not only make more people sharing ofhigh quality teaching resources, but also for enhancing the visibility of the school and to improvethe self-learning ability of students is certainly helpful.
