I need help on how to set up my database

I want to create a school management system, my problem is: how do i break up this data into chunks. How do I relate the students and their courses.

I decide to create a many to many relationship to relate this data like this

  • Student_Courses StudentID CourseID

I dont know if this is the best solution to relate each student to their courses, because i was thinking. This will have me select same student several times into table in order to assign him to a different course.

If you know a better way to relate this data or will have the time to guide me on how create this database, Please help, for any contribution will be resourceful. Thanks

If each student is (potentially) associated with more than one course, this seems like a good implementation.

I'm not sure what you mean by "select same student several times into table in order to assign him to a different course". Associating a particular student with a certain course should only require one new row added to the "Student_Courses" junction table.

If you still have trouble, it might be helpful if you posted the complete DDL for the schema. And perhaps the query code you will use with it.
