I feel like I learned a lot about SQL very easily and quickly, from the introduction to the application. Thank you. If I'm aiming to become a backend developer, how should I study more about SQL?

Practice designing tables by referring to various example diagrams (Google it). I recommend making them as small as possible but with a variety of options.
