I have a question with the above ^ response.
You said start by modeling the main entities.
main entities -- staff, rooms, patients, wards, services, etc.
Why would you write in rooms as a main entity?
10 wards with unique names/numbers each has up to 30 rooms. Wouldn't the rooms come underneath the wards?
I've got this task to do too, unfortunately I'm not very experienced in this topic either :P.
