Scenario 1:

The Prescriptions-R-X chain of pharmacies has offered to give you a free life time supply of medicines if you design its database. Given the rising cost of health care, you agree. Here is the information that you gather.

  • Patients are identified by SSN, and their names, addresses, and also ages.
  • Doctors are identified by an SSN, for each doctor, the name, specialty and years of experience must be recorded.
  • Each pharmaceutical company is identified by name and has a phone number.
  • For each drug, the trade name and formula must be reordered. Each drug is sold by a given pharmaceutical company, and the trade name identified a drug uniquely from among the products of that company. If a pharmaceutical company is deleted, you need not keep track of its products any longer.
  • Each pharmacy has a name, address, and phone number.
  • Every patient has a primary physician. Every doctor has at least one patient.
