The multiplicity 1..1 next to Pet Owners and 1..* next to Pets indicates that each Pet Owner can own multiple Pets, but each Pet is owned by exactly one Pet Owner. The best way to implement this one-to-many relationship in a database is by posting the primary key of Pet Owners as a foreign key in Pets. This allows multiple Pets to be associated with a single Pet Owner.
