Your question is Testing and SQL Foundations. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain how you would approach testing in an SDLC, including test metrics, bug lifecycle, and the differences between system and regression testing, and then describe how you would use boundary value analysis and SQL queries to support it.
