Draw an entity relationship diagram (ERD) for the following situation:
Whenever new patients are seen for the first time, they complete a patient information form that asks for their name, address, phone number, and insurance carrier, all of which are stored in the patient information file. Patients can only be signed up with one carrier, but they must be signed up to be seen by the doctor. Each time a patient visits the doctor, an insurance claim is sent to the carrier for payment. The claim must contain information about the visit, such as the date, purpose, and cost. It would be possible for a patient to submit two claims on the same day.
