Module 8: User Interface Design

The systems design creates a physical model of the system that fulfills the
design requirements defined during the systems analysis phase.

When you design the interfaces, create an interface that is easy to learn and use,
enhances user productivity, makes it easy to obtain help or correct errors,
minimizes input data problems, provides feedback, creates an attractive layout
and design, and uses familiar terms and images.

Input design begins with a description of source documents and the various
zones in a document, including the heading zone, the control zone, the
instruction zone, the body zone, the totals zone, and the authorization zone. The
data entry screen design uses input masks and validation rules to reduce data
errors. Input masks are templates that only limit user input so certain
combinations of characters and data validation rules can offer checks to ensure
that inappropriate data is prohibited from entering the system.

Data capture involves identifying and recording source data while data entry
involves converting source data into a computer-readable form and entering it
into the system. New technology offers a wealth of input devices to assist in the
entering of data.

Security and control are important to the system. Output control includes
physically protecting the data and reports, and controlling unauthorized access to
the data in the system. Input controls are used to limit who can input data into the
system.
