The functional dependencies that I note are as follows:
Pet ID --> Pet Name, Pet Type, Pet Age, Owner
Pet ID, Visit Date --> {Visit Procedure} (the set of visit procedures), note the use of procedure codes that repeat, but are listed in their own column
So, Is there are other functional dependencies? If so, what are they? If not, why not? Do you believe it would help to create additional attributes during normalization? If so, what are they? If not, justify why it's not needed. Please help me understand this.
