Using the Crow’s Foot notation, create an ERD that can be implemented for a medical clinic using the following 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.
Please remember your Part 2:
Create an Entity-Relationship Model (using information from your investigation of the DEEDS database) for the data collected during an emergency room visit for the following scenario.
A 21-year-old who delivered a baby in the ER
Caveat: You don’t have enough information to do the second part of this assignment perfectly. That’s ok. Do your best. If you run into a question about a business rule, make one up! I am looking to see that you are thinking about what data elements might be needed to capture the big picture of an emergency visit.
