Draw a class diagram for each of the following situations:

1. Whenever new patients are seen for the first time, they complete a patient information form that asks their name, address, phone number and insurance carrier, which are stored in the patient information file. Patients can be signed up with only one carrier, but they must be signed up to be seen by the doctor. Each time a patient visits the doctor, an insurance claim is sent to the carrier for payment. The claim must contain information about the visit, such as the date, purpose, and cost.

It would be possible for a patient to submit two claims on the same day.

2. The state of Georgia is interested in designing a system that will track its researchers. Information of interest includes: researcher name, title, position;

university name, location, enrollment; and research interests. Researchers are associated with one institution, and each researcher has several research interests.

3. A department store has a bridal registry. This registry keeps information about the customer (usually the bride), the products that the store carries, and the products each customer registers for. Customers typically register for a large number of products and many customers register for the same products.
4. Jim Smith’s dealership sells Fords, Hondas, and Toyotas. The dealership keeps information about each car manufacturer with whom they deal so that they can get in touch with them easily. The dealership also keeps information about the models of cars that they carry from each manufacturer. They keep information such as list price, the price the dealership paid to obtain the model, and the model name and series (e.g., Honda Civic LX). They also keep information about all sales that they have made (for instance, they will record the buyer’s name, the car they bought, and the amount they paid for the car). In order to contact the buyers in the future, contact information is also kept (e.g., address, phone number).
