Consider the following relation:
CAR_SALE (Car #, Date_sold, Salesman#, Commission%, Discount_amt)
Assume that a car may be sold by multiple salesmen and hence {Car#, Salesman#} is the primary key. Additional dependencies are
Date_sold â Discount_amt and Salesman# â Commission%.
Based on the given primary key, is this relation in 1NF, 2NF, or 3NF? Why or why not? How would you successively normalize it completely?
