I could give you some data, like this data a veterinarian might
have: DATA(OwnerID, FName, LName, StreetAdd, City, State, PetID, MicrochipNumber,
PetName, PetType, PetBreed), and a rule: One owner can have many pets, but a pet can only
have one owner. I would expect you to recognize the candidate keys (PetID and
MicrochipNumber), primary key (PetID would be the best choice, some pets might not have a
microchip), and any determinates (PetID and OwnerID), and whether the table DATA is
normalized (it is not).
