Required:

Based on the narrative, construct a comprehensive REA diagram describing your company's database (revenue cycle only). You may repeat a box for an individual entity if necessary to make your drawing neat. The owner would like for you to consider that, eventually, as new stores are opened, he/she will have store managers in each store that will perform the tasks he/she now performs. As a result, the system should be planned to always store information about the employee associated with transactions, whether that employee enters information, performs a task (such as delivery) or formally authorizes the transaction.

Prepare the context diagram and the level 0 DFD.

Davenport Customized Computers, Inc. (DCC) builds customized computers and related equipment for clients throughout the United States. DCC targets small businesses and at-home workers. Customers can order over the Internet and DCC will build and ship the finished product when completed, usually within two working days. DCC keeps up with all of the latest innovations. DCC also offers a variety of pre-built computers ready to ship within one hour of an order. DCC does not produce hardware components; rather, it orders all sub-components from reliable vendors and assembles the electronics at a plant located in Minneapolis, Minnesota. While computers ordered from DCC are noted for their excellent quality, DCC also prides itself in offering the best customer service in the world. Currently, DCC employs approximately 1,800 full-time employees. DCC's five year plan is to increase its workforce to 10,000 full-time employees and build four additional assembly plants across the United States.

Hints: - Assume that all cash receipts go into one account. - If a new customer places an order, the sales clerk or the customer must enter some basic information such as the customer's name, address, etc. - A particular sales order is always delivered and invoiced all at the same time. Deliveries include information for only one Sales Order.
