A busdriver needs to know if he should allow students at a corner onto the
school bus. Create a formal data design of the bus.

What could be important:
How many students fit on the bus?
How many students are on the bus?
What are the boundaries of the bus's route?

Data design of the bus:
+----------------------+
| Schoolbus            |
+----------------------+
| int maxCapacity      |
| int currentOccupants |
| int northWestCorner  |
| int northEastCorner  |
| int southWestCorner  |
| int southEastCorner  |
+----------------------+

(Keep in mind, there are other possible designs, less detail is fine)

A storeowener is planning on selling books on-line, create a formal data design
that will allow the store owner to track how many copies are in stock for each book, how many
copies have sold, and how much each book costs.

What's important:
current stock
how many sold
price
title
author

Formal design:
+------------------+
| Book             |
+------------------+
| String title     |
| String author    |
| int currentStock |
| int numSold      |
| double price     |
+------------------+
