This schema covers the basic entities needed for a school management system. Here are some explanations:

  • Students, teachers, and parents have personal information stored in their respective tables.
  • Classes are defined with a class name and section.
  • Subjects represent the different subjects taught in the school.
  • ClassSubjectMapping associates teachers with the subjects they teach in specific classes.
  • Enrollments link students to classes, capturing the enrollment date.
  • Grades store the exam results for students in different subjects.
  • Attendance records the daily attendance status of students in classes.

Depending on the specific requirements of your school management system, you may need to expand or modify this schema. Consider additional features such as timetable management, library management, extracurricular activities, or any other information relevant to your school.
