1 Introduction
For the student performance management system, make full use of modern information technology means. The development trend of student performance information management is informatization. Information management in the information age requires deepening the reform of the information management system and means, and fully using informatization means. Carry out comprehensive work on the student performance management system, build a student performance management system, realize the informatization of the student performance management system, make full use of the advanced student performance management system to manage student performance information, personal information and other information, and strengthen student performance management The perfection of the system platform, through the sharing of network resources and information, and the use of computer means, will gradually realize the systematization and networking of the student performance management system. For student performance information management, only by using this network trend can we move forward in the wheel of the times. The farther we go, the better we develop.
2. Technology stack
Python Django
MySql
HTML，Javascript
3. Functional analysis
This system is developed in top-down steps, and its basic functions are as follows:
This topic requires the implementation of a student performance management system. The system mainly includes three modules: administrator, students and teachers.
(a) Administrator; the administrator enters the main functions of the system including home page, personal center, teacher management, student management, announcement information management, course type management, course information management, course selection information management, grade information management and other functions and performs operations.
(b) Teachers: The main functions of teachers entering the system include home page, personal center, announcement information management, course information management, course selection information management, grade information management and other functions and perform operations.
© Students; The main functions of students entering the system include home page, personal center, announcement information management, course information management, course selection information management, grade information management and other functions and operations.
4 System design
4.1 Software function module design
The overall function of the system is shown in the figure below:
4.2 Login registration module
Users need to enter the system by filling in their own account number and password. If the user does not have a login account, he or she needs to register first. The user enters the account number and password on the registration page, click Register, enter the information required by the registration form, login password and confirmation password as required, click After registration, the system first determines whether the "Password" and "Confirm Password" entered by the user are consistent. If they are inconsistent, the user needs to re-enter them; if they are consistent, the registration is successful. Then enter the personal account and password just registered and click the "Login" button, and the display "Please wait while logging in." If the login information is correct, the system will jump to the idle product list interface; if the login information is incorrect, "Login failed" will be displayed. The login registration algorithm flow chart is shown in Figure 4.2 Login registration flow chart.
If the web backend administrator logs in correctly, he can view the user's modification of user information, view orders and other operations; if the input is incorrect, there will be no feedback and he will log in again. as shown

4.3 Database design
After the previous system analysis, we now enter the design stage. In this process, we need to analyze the data abstractly, understand the relationships in the data clearly, and then design the conceptual structure and logical structure. Because MYSQL can complete various database queries with extremely high efficiency, and can make stored procedures more convenient. At the same time, it can make database management and system management clearer and more convenient. In addition, the system is supported by Web technology, allowing users to easily publish data to Web pages. Therefore, this system uses MYSQL for database storage management and maintenance.
