I was studying only the front-end, but I found this course at the moment when I wanted to learn a little about the back-end. I recently saw a sentence in the NextJS official documentation that recommended the supabase DB, and since it was a free course, I took it without hesitation. I didn't know much about databases, but I was able to understand it easily! There were also lecture notes, so I was able to focus on the lecture. Thank you for the great lecture!
