Your manager provides you the following information about a database for a chain of
drug stores:
• a drugstore sells drugs prescribed by doctors to patients,
• each drugstore in the chain is identified by a store name, address, and a
phone number,
• patients are identified by a patient id, and their names, addresses, and ages
must be recorded,
• doctors are identified by a doctor id. Each doctor’s name, specialty, and years
of experience must be recorded,
• each drug is made by a pharmaceutical company and sold to the drugstore.
The drug’s trade name identifies the drug uniquely from among the products
of that company. For each drug, the trade name and formula must be
recorded
• each pharmaceutical company is identified by name and has a phone
number,
• every patient has a primary doctor,
• every doctor has at least one patient,
• each drugstore sells several drugs and has a price for each. A drug could be
sold at several drugstores, and the price could vary from one drugstore to
another,
• doctors prescribe drugs for patients. A doctor could prescribe one or more
drugs for several patients, and a patient could obtain prescriptions from
several doctors,
• each prescription has a date and a quantity associated with it. You can
assume that if a doctor prescribes the same drug for the same patient more
than once, only the last such prescription needs to be stored,
• pharmaceutical companies have long-term contracts with drugstores. A
pharmaceutical company can contract with several drugstores, and a
drugstore can contract with several pharmaceutical companies. For each
contract, you have to store a start date, an end date, and the text of the
contract,
• drugstores appoint a supervisor for each contract. There must always be a
supervisor for each contract, but the contract supervisor can change over the
lifetime of the contract,
• if a pharmaceutical company is deleted, you need not keep track of its
products any longer.
