Database choice for creating two connected tables?

Question

I have to database tables \"Courses\" and \"Students\".

• Courses table has columns (\"_id\", \"course_name\", \"course_number\").
• Student table has column

Answer 1

There is m to n relationship between Courses and Students. To map a m to n relationship you need a third table.

courses_students
----------------
id_student
id_course

courses
----------------
id_course
// other fields

students
----------------
id_student
// other fields
