Project Description

This system is the design and implementation of a student course selection management system based on the WeChat applet. The design is based on the B/S architecture model, using JavaScript, CSS, java language, etc., and the background database design uses Mysql. The system is mainly implemented in two parts: the WeChat applet is the client, and the server is implemented using SSM (Spring+SpringMVC+Mybatis) as the Java background of the design idea. The main function of the WeChat Mini Program client is to display and use data. The main function of the server side is to monitor the data.

The student course selection management system is mainly divided into three permissions: students, teachers, administrators

After logging in to their account on the Mini Program client, students can check their personal information, course selection information, check courses, check grades, and change passwords. Among them, for the course that the student has already selected, if he repeats the course selection for this course, he will not be successful, so as to avoid data duplication;

After logging into the account, teachers can view their personal information, view course information, score students who choose courses, and change passwords;

After logging in to the account, the administrator can view, add, modify, and delete students, as well as view, add, modify, and delete lecturers, as well as view, add, modify, and delete courses, and can reset passwords, etc.

System database table structure design

Next, we will introduce the table structure of the database design of this system. The following are the main database tables in the system and the function of each database table.

Table 1 Main database tables of the system

Table Name	Chinese name	functional module
college	college table	Faculty Information Module
course	Class Schedule	Course Information Module
role	role table	Role Information Module
selected course	Course Selection Information Form	Student Course Information Options Module
student	student table	Student Information Module
teacher	teacher table	Faculty Information Module
userlogin	User Information Form	User login information module

Well, it’s winter, my hands are freezing when I’m typing, I’m too lazy to draw a watch, everyone will just watch it. …

The college information table is mainly used to record the information of each secondary college.

Table 2 Faculty Information Form

Table 3 Course Information Form
