To fulfill the requirements, we need to implement at minimum the following forms.
Table 7.1. Core requirements for our sample application
| Edit services table | Maintain an inventory of the services the company offers. |
| Customer orders | Maintain a record of customer orders. |
| Customer complaints | Maintain a record of customer complaints. |
In addition to developing a page for each of the core requirements, we'll implement the following pages for user convenience.
Table 7.2. Additional features for our sample application
| Main Menu | The point of entry for the application that links to all other pages. |
| Edit priority table | Every complaint must be assigned a priority level. This page allows the user to edit the valid priority codes that may be used in the complaints page. |

| All information about customers | This page shows all orders and all complaints for a given customer on one page. |
The user should be able to navigate from page to page as shown in the screen flow diagram below.
