The management of student performance is an important part of the management of middle school students in colleges and universities today. The level of grades determines the level of grade points, which is related to the acquisition of student scholarships, the acquisition of guaranteed research places, and the test of learning ability. Therefore, it is very important to have a score management system with different permissions, security protection capabilities, and good storage capabilities. The performance management system is designed to have different permissions for different users, including teachers and students.
