Welcome to your interview.
The question is on your right: DBMS Principles for Data Integrity. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Explain the core principles of DBMS and how they apply to verifying data integrity in your test scenarios.
