My database is a Reservations System. I want the following to happen:
1. Once a booking has been made it CAN be modified and cancelled.
2. Once the ticket has been issued (printed) it CANNOT be modified.
3. Once reprinted the words "DUPLICATE" should appear on the face of the reprinted ticket
4. Keep track of who made what changes.
