The design and implementation of exquisite course website

Based on the analysis and research on the exquisite course website, a more reasonable and practical solution of design and implementation is put forward. Breaking the fixed mode of the online testing subsystem in traditional exquisite course website realizes the dynamic and random questions extraction as well as the dynamic changes of the item options. At the same time teaching_video on demand using Nginx server to load balancing not only increases the number of concurrent connections, but also reduces the response delay of the end-users. In conclusion, the real-time distance education subsystem based on Red5 server provides a virtual classroom for communication between teachers and students while also promoting the development of internet-based higher education.
