Each client (patient) has a unique Code, name, home-phone, work-phone, address, and birth-date. Each client is assigned to one dentist. All future visits will be to the same dentist. A client can be insured or self-paying. An insured client should have an insurance company-name, and company-Phone, while a self-paying client must have a bank-name and a bank account.

Each visit of a client is described by a date, type, action, fee, and date-of-next-appointment
