Command Patterns

Command patterns are determined by the command structure chosen for the application. A command is any function performed by the application based on user input. Commands that perform similar functions may be grouped together. The collection of commands and command groups make up the command structure of the application.

Command patterns can be combined with navigation patterns and content patterns to design the complete layout for your application.

Guidelines

When designing an application, it may be unclear what the command structure should be.

• Start by assuming a simple command structure and select an associated command pattern.
• As the design evolves, if the selected pattern becomes inadequate for completing the primary tasks of the application, consider a pattern for a more complex command structure.
