Prerequisites

Before you begin designing a GUI, you need to complete or have an understanding of a minimum list of 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 to GUI design. The list does not represent a sequence. It shows only a set of prerequisites that can be satisfied in a number of different sequences. 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.

• An understanding of the tasks that the user performs with the application, which is usually determined from previous phases of a life cycle development
• A 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
