I am studying SQLD, but I had a hard time studying because I had never actually used SQL. However, through this lecture, I was able to practice in various ways and easily understand the code! And what I thought was so kind was that it didn't just teach me about SQL and end there, but explained the role of SQL in the development process, so I was able to understand it in a bigger context. It was even better when it explained the backend and frontend at the end of the lecture👍🏻👍🏻
