Which concept is a matrix that maps combinations of conditions to actions?

• A. Decision Table
• B. Cursor
• C. Check In
• D. Construction

Answer: (A)

A decision table expresses rules as a matrix that maps combinations of conditions to actions. By laying out each possible set of conditions in rows and the corresponding action or outcome in the adjacent column, it makes complex conditional logic easy to read, validate, and implement. This structure helps ensure all relevant scenarios are covered and reduces ambiguity when coding the behavior. For example, in a payment system, conditions like card valid, funds available, and fraud check passed can each combine to yield actions such as approve, decline, or flag for manual review. A cursor, in contrast, is just a way to iterate over query results and does not define conditional rules. Check-in relates to recording changes in a version control system, not mapping conditions to actions. Construction is a general term that doesn’t describe rule mapping.
