1. Course selection system source code description This is a course selection system source code with relatively complete functions, which is of great learning value.

2. System Analysis In this system, there are three types of users: system administrators, teachers and students. Three different users have different operation permissions and operation contents.
This course selection system gives teachers a great deal of autonomy. The system administrator is only responsible for adding the personal information of students and teachers as well as the classroom information of the teaching building to the system. The system administrator is not involved in setting up courses, selecting courses, etc. Everything is done by teachers, students, etc. on the website. The system administrator sets a course selection time period. Before the time period is reached, teachers can offer courses; after the time period is reached, students can log in to the website to select courses.
Teacher users can open courses after logging in to the website, and edit class time and location for their courses. When a time and location conflict occurs in the system, the system will report and recommend a time and location to the teacher user. Each course can be compulsory or elective. The teacher sets a credit for each course and can give points after the course. If the student passes, the student will receive credit for the course.
For student users, in addition to the required courses, each student must choose at least two elective courses. Students can lock their course selection information to avoid accidental modification. After the course selection period has passed, the system automatically locks the students' course selection. The system can generate a student's own class schedule based on the student's course selection information. After the course, students can log in to the website to check their scores and credits.
According to the above requirements, the operation functions can be divided into two categories: one is general operation, which mainly realizes user login, logout and password change, etc.; the other is customized different operations for different users.
