To handle the customer category management requirements, we need to do the following:

1. Define the Customer Category table.
2. Create the pages (user interface) that will handle the Customer Category entity (the List and Card pages).
3. Add a new Customer Category field to the standard Customer table.
4. Add the new field to the standard Customer Card page and add some actions to the Customer pages to handle some tasks.
5. Create the business logic to handle the requirements.

In the next sections, we'll see the definitions and implementations of the various objects in detail.
