Description
The most important task at the rolling Thunder Bicycle
company is to take order for new bicycles. Several features
have been included to non experts to select a good bicycle.
As the bicycles are built, the employees record the
instruction on the assembly form. When the bicycle is
shipped, the customers are billed. Customer payments are
recorded on the financial forms. As the components are
installed on bicycle, the inventory quantity is automatically
decreased. Merchandise is ordered from supplier and
payments are made when the shipment arrive.

Customer orders.: Customers can place orders
directly with the company, or they can order with
the assistance of a local bicycle store.
Bicycles are assembled and shipped in about two
weeks.
Basic components are ordered in advance
because of shipping delays.
Inventory count is maintained by the computer.
As workers assemble a bicycle, they record the
use of each component.
Customer payments can be made at the time of
purchase, or as monthly payments.
Suppliers are paid only after receipt of shipments.

Homework
A dentist who runs a small office by himself, three hygienists
and receptionist want a database to schedule appointments.
He has a commercial billing system to handle payments and
insurance but appointments are currently written on paper
form(date & time, Dr. name, patient name, fee and procedure
[i.e. cleaning, X-ray, filling and so on...]). He wants to add a
little more detail and list all the procedures planned, the
estimated fee for each procedure, and the estimated
insurance coverage. The base fees should be stored with the
procedures, but the insurance amounts are highly variable
and will be entered by the receptionist who can estimates
from the billing system. The system also has to track the
patient’s phone, email and how he/she wants to be notified.
Eventually, it could send e-mail messages to patients as
remainders.
Create the class diagram for this case.
