Read the following business rules carefully and use common sense when necessary to come up with a good database design as follows: 1- First, develop an ER model. Make sure to use meaningful entity names and relations. 2- Translate ER model into a set of tables, relations and constraints. 3- Label appropriate columns as primary keys and foreign keys. Business rules: A patient can make many appointments with one or more doctors in the clinic, and a doctor can accept appointments with many patients. However, each appointment is made with only one doctor and one patient. Emergency cases do not require an appointment. However, for appointment management purposes, an emergency is entered in the appointment book as “unscheduled.” If kept, an appointment yields a visit with the doctor specified in the appointment. The visit yields a diagnosis and, when appropriate, treatment. With each visit, the patient’s records are updated to provide a medical history Each patient visit creates a bill. Each patient visit is billed by one doctor, and each doctor can bill many patients. Each bill must be paid. However, a bill may be paid in many installments, and a payment may cover more than one bill. A patient may pay the bill directly, or the bill may be the basis for a claim submitted to an insurance company. If the bill is paid by an insurance company, the deductible is submitted to the patient for payment. nd relations as far as one to one, one to many, many to many. etc.

Our model accounts for various core entities within the healthcare clinic, including patients, doctors, appointments, visits, medical histories, bills, payments, and insurance claims. Each entity is designed with specific attributes tailored to its role in the healthcare ecosystem. These attributes facilitate the recording, tracking, and management of relevant information.
The relationships between these entities are central to the database design. Patients can make multiple appointments with doctors, and doctors can accept appointments from various patients. Each appointment is intricately linked to a single patient and a single doctor, promoting clear assignment of responsibilities and enabling efficient appointment management.
To address emergency cases, our model accommodates unscheduled appointments, ensuring prompt attention to critical medical needs while preserving the integrity of appointment records.
The database design also takes into account the patient's journey through the clinic. With each visit, the patient's medical history is updated, allowing for a comprehensive understanding of their healthcare needs and ensuring continuity of care.
