hi,
I have a ER Diagram about the pharmacy database.
but I have problems understanding the relastionships between the patient and the doctor,Idon't understand what "priphys" means in the diagram and why does it have a relastion with prescription(shown with number 3 in the image)
also what does the arrow mean in the diagram(shown with number 2 in the image).
what does the number 1 in the image mean.

Just a blind stab in the dark, but it doesn't stand for Primary Physician?

priphys is association entity between physician and prescription
numbers indicate relationships among entities
