In data modeling, which of the following is NOT one of the standard ways to classify an action assertion (business rule)?

Introduction / Context:
Action assertions capture dynamic business rules that constrain or guide actions in a database or application. Common classifications group these rules by their purpose.

Given Data / Assumptions:

• Typical classifications include Condition, Authorization, and Integrity Control.
• We seek the option that is not a standard classification label.

Concept / Approach:
Condition rules specify prerequisites or states that must hold. Authorization rules regulate who may perform actions. Integrity Control rules protect data validity during actions. “Enabler” is not one of the canonical categories in common modeling texts.

Step-by-Step Solution:

Verification / Alternative check:
Business rules literature consistently uses the three listed categories; “enabler” may be used informally but not as a formal class.

Why Other Options Are Wrong:
They are established categories of action assertions.

Common Pitfalls:
Mixing ECA (event-condition-action) terminology with action assertion classifications.

Final Answer:
Enabler
