Use the Dell website (www.dell.com) and look at "Building and pricing a computer" (NOT buying) as the use case. Using this use case, generate a fully-developed use case description, an entity-relationship diagram (just to cover the data needed for this use case), a domain model class diagram, a data flow diagram, an activity diagram, and a system sequence diagram for this process. DO NOT include purchasing the computer, this is a different use case!
NOTE: In order to do this assignment properly, you must actually go to the Dell website and follow the process for customizing and pricing either a laptop or a desktop, noting the process as you go along. Therefore you will have to go down into the "customizing" choice on a given computer and pay attention to what happens when you are configuring a machine. Keep in mind this is ONLY to customize and price a computer, NOT purchase it, so there should not be anything about a cart in the use case! Do not make the process up - use how the Web site works as a guide!
