Designing a Graphical User Interface › Graphical User Interface › Prerequisites

Prerequisites

Before you begin designing a GUI, you should have either completed or have an understanding of certain tasks. However, the specific task list can vary depending on the information engineering techniques of the life cycle being used.

The following list offers a starting place of prerequisites. As you become more familiar with designing GUIs, or select a life cycle that works best for your needs, you may prefer a different set of prerequisites. For more information about the alternative life cycles that use information engineering techniques, see the Client Server Design Guide.

• An understanding of the tasks that the user performs with the application, which is determined from previous phases of a life cycle or by interviewing users as you design the interface
• A partial or complete data model defined with one of the Data Model tools
• One or more procedures defined with the Dialog Design tool
• Views for one or more procedures defined with the View Maintenance tool or the Action Diagram tool
• A business system defined with the Business System Definition tool
