The kennel’s function is to look after dogs while their owners are out of town. To help with the running of the kennel, they maintain a spreadsheet of the name, breed, and age of each dog who is staying with them, as well as the name, address and phone number of each dog’s owners. The database also stores special instructions for the care of each dog, as well as which kennel room the dog is staying in, and a note of the unique microchip number which each dog has implanted in their neck. Every dog must have a chip number. Vet notes are added to the spreadsheet if a dog is seen by the vet and vet notes must be associated with a single dog. The current way in which the data are stored is shown in the table below. Note that each person can own more than one dog and each dog can have more than one owner. The vet columns are empty unless the dog has been seen by the vet. A vet visit cannot exist without a dog, of course.
