I'm waiting for your answers)

corrected a bit.
what is the best way to link table "Hall" and "Sector"???

Answer 1

1. Why is there a "hall" field in the ticket when it is in the session?
2. Why is there a "sector" field in the ticket when it is included in the price?
3. Why is the "sector" field in the price unrelated to anything?
4. Why in the Field1 session?
5. What determines the price? Perhaps there should be a table of the form (room, sector, date interval, price) or (session, sector, price)?
