  2. Main objects • The rolling Thunder Bicycle Company builds custom bicycles. • Its Database application is much more complete and provides an example of how the pieces of database system fit together. • The task is similar to any other business.

  3. 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.

Basic company operations • 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. • Suppliersare paid only after receipt of shipments.

  13. Questions

  14. 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, feeand 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.
