Draw an ERD for a scenario in which patients visit doctors. It is possible that a patient is visited by more than one doctor.
Create DOCTOR and PATIENT entities and add at least four attributes to them including a primary key. Create an implementation ready ERD with all appropriate connectivities and cardinalities. Justify your choice of cardinalities with real world examples. In case you need to add any new entities, add at least two attributes apart from their primary keys to describe the entity.
