    • Username
    • Password
    • Email
    • EnrollmentDate

This schema covers the basic entities needed for an Intelligent Tutoring System. Here are some explanations:

  • Students and tutors have information stored in their respective tables.
  • Courses are defined with details such as name, description, and the tutor responsible for the course.
  • Lessons and assessments are associated with courses, capturing content, order in the course, passing scores, and other relevant details.
  • StudentCourseEnrollment records when a student enrolls in a course.
  • StudentLessonProgress tracks the progress of students through lessons, including completion status and last accessed time.
  • StudentAssessmentResult stores the results of student assessments, including the score and attempt date.

Depending on the specific requirements of your Intelligent Tutoring System, you may need to expand or modify this schema. Consider additional features such as personalized recommendations, user feedback, collaborative learning, or any other information relevant to your tutoring platform.
