User Interface Design

The user interface provides interaction between the user and the application. Choose one of the following options to document the design of your user interface:

1. Develop a layout diagram or prototype of the windows used in the application. (Refer to page 430-431 of your textbook)

2. Develop a windows navigation diagram (WND) that maps the events and relationships between the major forms in your application.

Controls

Describe at least three control mechanisms that you will implement to prevent/detect possible errors in the system. These may be in the form of user interface controls, business rules, or flow logic. For each control object

1) explain the type of control object it is,

2) provide a brief description, and

3) explain its role or function in the system and how it will help prevent/detect possible errors. An example of a user interface control: the input field for the order amount will only allow numeric data. A business rule: an order must include a minimum of 1 item. Flow logic: if the user has entered an invalid user name or password, redirect them to an error screen.
