business rules
statements specifying constraints and relationships between components of a user interface. For example:
- The Age field may not be less than zero (a constraint on a numeric field widget).
- When the Credit Card Expiration Date is less than Today’s Date, the Credit Card Expiration Date will be displayed in red, and the Submit Order button will be displayed in its unavailable state (a relationship between different user interface components).
Business rules are meant to be a design specification written in plain language. They often accompany dialog box and simple form specifications.
