Thank you

you are connecting entities with lines and by drawing relationship know(diamond box)in those lines u have to write 1 like that.On the right hand side line before the diamond box you have to write 1 and on the left hand side line after the diamond box write one(it means one to one relationship).If you still have doubt mail me -roshin2608@gmail.com

you can write verb and phrases inside it

Thank you.Yes you can write it in capitals.

Same here 😅

for doctor to patient the cardinality is 1:N(one to many) and for patients to medicine it is N:N(many to many)

Thank you

You can assign a Superclass entity "Person" and keep "Dr." and "Patient" as Subclass entities.

Yes you can add hospital as an entity and give attributes like hospital name, location,mail id,landline number,an id etc...

It is an entity because it's a buliding and it's physical existing.
