The enterprise for this project is an excerpt from the UML design of the Project 2 Canonical Solution. Specifically, we will ignore/delete the Color, Body Style, and Manufacturer classes; you do not need to incorporate these fields in other places, e.g., you do not have to add a "color" field to the Automobile class -- simply assume that color is no longer part of the enterprise. The remaining six classes -- Model, Trim, Package, Feature, AvailablePackage, and Automobile -- form the requirements for this project.
