This phase is the discovery phase, no coding is required. You will be using your knowledge of object oriented principles to complete this phase.

1. List all of the classes you will need to capture the data required for the project. Be sure to label each class as concrete or abstract as well as all child classes that will inherit from a parent class. Be sure to include the following for each class:
   1. The name of the class and whether it is concrete or abstract
   2. If the class is inheriting, the name of the parent class
   3. A list of all properties in the class
   4. A list of all methods in the class and a brief description of the functionality of the method. You do not need to include the signature at this time. Some examples:
      1. GetCustomer is a method that will retrieve all customer data for a given customer
      2. UpdateInventory is an abstract method used to update the various types of inventory items
