A health care organization keeps track of its doctors and outpatient locations.

For each outpatient location it keeps track of the OLID (unique) and OLName, and the following additional requirement:

Each doctor works at either one outpatient location or at none (strictly working in the

main hospital), and each outpatient location must have at least one but can have many

doctors working at it.

E2.2c Additional requirement

Each doctor works at exactly one outpatient location, and each outpatient location must

have at least one but can have many doctors working at it.

E2.2d Additional requirement

E2.2k Additional requirements

Each doctor works at between one and many outpatient locations, and each outpatient

For each occurrence of a doctor working at an outpatient location, we keep track of the

location).

E2.2l Additional requirement

Each doctor works at between two and four outpatient locations, and each outpatient location has between three and ten doctors working at it.

E2.2m Additional requirements

location has exactly one doctor managing it.

E2.4 Create the ER diagram based on the following requirements:

A health care organization keeps track of outpatient locations and examination rooms within the outpatient locations.

For each outpatient location it keeps track of the OLID (unique) and OLName.

For each examination rooms it keeps track of the ERoomNumber (unique within its outpatient center, but examination rooms in different outpatient locations can have the same ERoomNumber), and ERoomSize. Each outpatient location must have at least one but can have many examination rooms.

Each examination room is located in one outpatient location.
