Considering the scenario in the previous problem, assume the following rules are also implemented for this system:
There are two types of Pharmacists – new pharmacists and seasoned pharmacists. A new pharmacist may be a student or a professional, or could be both. There are other types of pharmacists but those are not needed in this system description.
A Cashier can be an intern or a professional. If they are an intern, they can be an undergraduate or graduate intern, but not both. These are the only types of interns. If they are a professional, they can be a trainee or a seasoned cashier, but not both. These are the only types of professionals as well.
A Pharmaceutical Rep can be from a research lab, or an educational lab, or both. There are other places that are possible, but we're only concerned with these two here. If they are from an educational lab, they can be from a Minority-Serving Institution (MSI), or a Predominantly-White institution (PWI). There are no other options of institutions available.
