Data Access · interview question
A teammate submits shaky row mapping code. Which review comment is the strongest?
Multiple choiceHardchapter-11-curatedpremiumdata-accessrow-mapping
Answer and explanation
Correct answer
C. Make the rule clearer and easier to explain. Translate raw rows into domain-oriented structures or DTOs so the rest of the code does not depend on tuple positions forever.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. Letting raw row tuples leak upward makes the service layer harder to read and easier to break.
