Online course arrangement and elective system
Abstract: Computer is already an indispensable component of life. People can manage the affairs with the help of computer that they should do it all by manpower in the past. It can not only improve the efficiency, but also save the money. Because school were using the outdated elective system, users always met a lot of terrible errors, such as "BROWSERS INCOMPATIBLE", "POOR PERFORMANCE", "UNSAFE". The advantages of this system was analyzed all aspects of the unreasonable old methods, raised a improved and optimized scheme, solved these problems with integrate and experiment. First, This thesis analyzed the various aspects of the functions which need to be achieved., such as compatibility of code, rights management of users, conflictions, process reliability safety. Then, with the various needs of actual purpose, this thesis deeply analyzed the irrationality of existing solutions, such as conflict judging too dependent on program logic and server resources, unreasonable rights management, and put forward corresponding programs to improve. This thesis also tested the feasibility of the programs by experiments, checked the need of server environment and server configurations, also improved the process. Finally, this thesis determined the program of code, and explaned each part of the principle in detail. On the other hand, this system reformed some operations, provided a good user experience. In the end of this thesis, it advanced some deficiencies of process and its optimization direction. Users may no longer face the embarrassment of historical factors.
Keywords: online course arrangement and elective system; user experience optimization; to achieve process improvement
