Database Model Draft

Create a database model according to the following steps:

• Create a simple class diagram containing three classes: Vehicle, Car, and Truck. Provide two attributes for each of these three classes.
  • Create a rough sketch of a relational table that will store the objects belonging to the aforementioned three classes.
  • Ensure you have tried all three options—single table, two tables, and three tables—in your database design.
  • Enter two objects per table, corresponding to the classes.
• Use the two-table design to recreate a Car object.
• Repeat the preceding step to recreate a Truck object.
• Create a simple association relationship in a separate class diagram showing Driver and Car.
  • Apply a multiplicity of 1 on the driver side and N on the Car side.
• Add/modify your table designs to handle storing of two objects belonging to Car and two belonging to Driver.
  • Modify the multiplicity on the Driver side to N. This makes it a many-to-many multiplicity.
• Modify your table designs to handle this multiplicity and show where and how the KEYS or IDs will have to be placed.
• Create a class diagram corresponding to the tables you have designed. Stereotype all classes on that class diagram as <<table>>.
