From discussions with hospital staff, reviewing hospital documents, and studying existing information systems, the study team developed a list of business rules describing the policies of the hospital and nature of the hospitals operation that govern the relationships between these entities. Some of these rules are:

1. A facility maintains one or more diagnostic units (radiology, clinical laboratory, cardiac diagnostic unit, etc.).
2. A facility contains a number of wards (obstetrics, oncology, geriatrics, etc.).
3. Each ward is assigned a certain number of staff members (nurses, secretaries, etc.); a staff member may be assigned to multiple wards.
4. A facility staffs its medical team with a number of physicians. A physician may be on the staff of more than one facility.
5. A physician treats patients, and a patient is treated by any number of physicians.
6. A physician diagnoses patients, and a patient is diagnosed by any number of physicians.
7. A patient may be assigned to a ward (outpatients are not assigned to a ward).
8. A physician writes one or more orders for a patient. Each order is for a given patient, and a patient may have many orders.

If you don't have in-depth knowledge about the topic then don't answer it.)
