Database Design

I need to design an ERd for a student teacher scheduler program. The program would let the following to take place :
the teacher would be able to set his office hours
the teaxcher would be able to set free times for meeting students
the student would be able to read teacher meeting time periods and reserve one of them.

what is the best way to design that, how many tables do I need.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would say 4 tables: Students (id, name, whatever else), Instructors (id, name, whatever else), AvailableHours (id,instructor_id,begin available datetime, end available datetime) and Scheduled (available_id, student_id)

That seems like poor database design IMO. Instead you should use something like (instructor_id, day (mon, teus, etc), begin (08:00 for example) and end (13:00 for example)

Then for an instructor you might have 3 rows:
3,Monday,08:00,12:00
3,Wednesday,09:00,12:00
3,Friday,13:00,15:00

This is especially helpful if an instructor has office hours say from 9am to 11am and 3pm to 5pm the same day.
