Which method uses existing PAF columns?

• A. Method 1
• B. Method 2
• C. Method 3
• D. None

Answer: (C)

Using existing PAF columns means relying on the fields already defined in the PAF schema rather than creating new ones. This approach keeps data within the established structure, so the method reads from and writes to those preexisting columns, preserving the defined data types, constraints, and meanings. Because of that, you can perform the task directly on stored data without changing the table layout or adding new columns, which reduces maintenance and the chance of inconsistencies. This method is efficient and safer for data integrity because it leverages what’s already validated and in place. Other approaches might require introducing new columns or using temporary storage, which adds complexity and potential drift between the computed results and the underlying schema.
