Whenever patients are seen for the first 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 file. Patients signed up to be seen by doctor must be a member of at least one insurance carrier. Each time a patient visits the doctor, an insurance claim is generated and will later be sent to the carrier for payment. The claim must contain information about the visit, such as date, purpose, and cost. It would be possible for a patient to submit two claims on the same day.
Draw an ERD that shows the entities, attributes, primary key(s), foreign key(s), and relationships. Each relationship must be labeled.
- List all identifying relationships (if any).
- List all non-identifying relationships (if any).
- List all independent entities (if any).
- List all dependent entities (if any).
