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

For each doctor it keeps track of the DoctorID $($unique$),$ DoctorName, and DoctorYearOfMDGraduation $($year of graduating from medical school$)$

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

Each doctor works at either between one and many outpatient locations and each outpatient location must have at least one but can have many doctors working at it

For each occurrence of a doctor working at an outpatient location we keep track of the NoOfHoursPerWeek $($number of hours per week that a doctor works at an outpatient location$)$
