problem 4: A portion of the Baxter Aviation database is as follows: Aircraft (Aircraft ID #, Make, Model, #seats, total airtime, hours on engine) Village (Village name, Type of runway) Flight (Flight time, Flight date, Aircraft ID#, Flight#, Customer #) Destinations (Flight#, Village name) Customers (Customer name, House number, Phone, Customer #)

a) Identify the primary key for each relation.

b) Identify all foreign keys and the primary keys they reference.

c) List all the constraints that must be verified whenever a row is inserted into the Flight relation. (In other words, what are the specific integrity checks that must be made?) In your list, indicate exactly which attributes are being checked and the specific test(s) being performed on each.
