For each appointment (i.e., when there is an availability of a time slot for both a Patient and a Doctor), the date and time of the appointment must be captured. For each doctor, a number (unique), name, and phone number is captured. For each patient, a patient ID (unique), name, address, SSN, date of birth, and phone number is recorded. Tampa Clinic also wants to capture the medical history of each patient. A medical history consists of a number (unique), illness type, date, and treatment. Each patient may have more than one medical history, and a medical history belongs to only one patient. Each patient must have at least one medical history.
