Each drug is sold by only one pharmaceutical company, and the trade name identifies a drug uniquely from among the products of that company. If a pharmaceutical company stops production, we do not need to keep track of its products any longer. Each pharmacy has an identifier name, address, and phone number. Each pharmacy sells several drugs. A drug could be sold at several pharmacies, and the price could vary from one pharmacy to another.
