Answer 1

Heres the description
These cruises have a name, a duration of 2,3 days and a cost that varies between 600 and 1000. The cruises are repeatedly run along various standard routes starting at four different ports. The start date of each voyage, its starting location and its ships are recorded.
Customer book the cruises and SeadCruise need to record the customer name, gender telephone number, and address. Each time a customer name, gender, telephone number, and address. Each time a customer takes a cruise their cabin number and class (1st, 2nd) is recorded. Customer will also give an evaluation of the cruise (0, 5) SeadCruise need to recored the evaluation from each customer each time they take a cruise. It is not a requirement that that all voyages have passengers registered on them, and it is also not required that every customer has to have participated in a cruise. Each ship has a name, a port of registration and gross tonnage.
and also considering the querys like..
Find the voyages of cruises that have an occupany below a the average occupancy for voyage of that course.
I am come to the conclusion that the below tables are require. Would I be right in thinking this.
Cruise(CruiseNO, Name, Duration, Cost, Ports)
Booking(CruiseNO *, CustomerID*, VoyageID*, CabinNo, Class, Evaluation)
Customer (CustomerID, CustomerName, Gender, Telephonenumber, address)
Ship(ShipID, ShipName, Port, tonnage)
Voyage(Voyage_ID, Startdate, Starting_Location, ShipID*
Am i right that the above tables needs to be created?
