There are a lot of people associated with the hospital. Each Person could be associated with different Hospitals, and a Hospital could employ or serve multiple persons.

Doctor has some specialty, designation and location of his room. A doctor can examine, provide prescription and perform surgery/operation of his patient. A Doctor and a nurse can treat many patients. One patient is treated by 1 or 2 doctors, a senior doctor and a junior doctor.
The hospital consists of wards. Ward is a division of a hospital or a suite of rooms shared by patients who need a similar kind of care. In a hospital, there are a number of wards, each of which may be empty or have on it one or more patients. Each ward has a unique name and fixed capacity. Wards are differentiated by gender of its patients, i.e. male wards and female wards.
