The option for referential integrity between the Owner table and the Pet table is cascade and an attempt is made to update the row for Owner 005 in the Owner table (OwnerNum = 005) to have a new OwnerNum of 500. What is the result? (Use only the data in the question. Do not assume other data exists if it is not present in the tables below.) The primary keys are underlined. These are the OwnerNum column in the Owner table and the PetNumber in the Pet table. The foreign key is italicized. This is the OwnerNum column in the Pet table.

You have the following tables:
APARTMENTS (ADDRESS, CITY, STATE, RENTER_ID, RENTER_LAST_NAME)
RENTERS (RENTER_ID, FIRST_NAME, LAST_NAME)
What is the primary key for the APARTMENTS table? (It may be a composite key involving 2 or more fields) What are the foreign keys, if any?
What is the primary key for the RENTERS table? What are the foreign keys, if any?
What field in RENTERS can be eliminated so that the RENTERS table is normalized?
