Assignment Help:
Every School has many teachers and many students. Each student is assigned to one school and each teacher works for one school only. Each teacher teaches more than one subject but a subject may be taught by more than one teacher. The database should store the number of hours a teacher spent teaching a subject. Information held on each teacher includes his/her tax file number, name (first and last), gender and qualifications. The data held on each subject includes subject title and type. Each student can study more than one subject and a subject may be studied by more than one student. Data held on each student includes the student number, name (first and last), gender and date of birth. Each school is managed by one of its teachers.
