IIBA Exam ECBA Topic 4 Question 107 Discussion

Definitional rules are a type of business rule that form theories or produce information. They represent something that is fundamentally true or untrue about some concept within the organization. Unlike behavioral rules, which are about people's behavior, definitional rules constitute operational knowledge of the organization. They cannot be violated but can be misused. For instance, a definitional rule might be used to classify different categories of customers based on contractual agreements or order quantities.
