Draw an entity-relationship diagram (ERD) for the following situation:

Problem: Whenever new patients are seen for the ?rst time, they complete a patient information form that asks their name, address, phone number, and insurance carrier, all of which are stored in the patient information ?le. Patients can be signed up with only 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. Therefore, it would be possible for a patient to submit two claims on the same day.

The ERD created should include entities, attributes, relationships, cardinalities (max and min), and identifiers (primary and foreign keys). State all assumptions made in creating the ERD and provide a narrative in plain language describing what the ERD says.
