SQL vs NoSQL
"SQL or NoSQL?" is one of the most common questions in system design interviews, and one of the most poorly answered. Candidates either default to one without reasoning, or recite a generic comparison that doesn't connect to the actual problem. The right answer always depends on your specific requirements.
This lesson cuts through the noise. You'll learn the actual trade-offs that matter and see when each type shines, then practice the reasoning pattern interviewers want to hear.
