PHYSICALLY DRAW THE CONCEPTUAL DATA MODEL to model the scenario in each problem. Use the model constructs $($e$.$g$.,$ the material on the E$-$R model and the enhanced E$-$R model$)$ from chapters $2$ and $3$ as appropriate and follow the modeling conventions used in the example problems in the online lessons. Do not use the modeling conventions shown in Figure $2-22$ of the Hoffer textbook which illustrate a data model in Visio notation. Be sure to include all appropriate completeness constraints, disjointness constraints, and subtype indicators in your conceptual data models.

You should consider the three problems to be completely independent of one another. You may use any amount of space you find necessary to draw each model. Please insert your answer in the space following each problem. Each problem is worth twenty points.
