Data Access · interview question
A teammate submits shaky repository boundaries code. Which review comment is the strongest?
Multiple choiceHardchapter-11-curatedpremiumdata-accessrepository-boundaries
Answer and explanation
Correct answer
B. Make the rule clearer and easier to explain. Let repositories own query details while the service layer owns workflow and policy decisions.
Why
The best review comment anchors the change to readability, correctness, and future maintenance. If business rules and SQL are tangled together, both testing and change impact get worse.
