Introduction to Databases & SQL from a Senior Backend Developer

This is one of the best DB lectures in my backend development life. From the basic concepts of DB to queries that I had taken lightly, I got a lot of insight into "I can handle this much!" It was even better because it explained the principles, not the usage. Thank you for explaining the concepts of DB used in the field so easily😀

As a backend developer, he teaches you about databases, one of the CS basics, in a way that beginners can easily understand. Even if you don't have any prior knowledge, if you take the lectures in order, you will have no problem understanding them because they are introductory courses. Additionally, since he explains shallowly and broadly as befits an introductory course, I think I have a foundation for studying each part in depth to see which parts I am lacking. I liked that he always told me the goals of each lecture part first, so I knew which parts I should focus on. Also, as a senior backend developer, I liked the parts where he explained things using practical examples and always drew pictures to help me understand. The voice is not divisive, and the instructor's basics are solid, so the explanations proceed smoothly. Thank you for letting me listen to this level of lecture for free! I also subscribed and liked the instructor's YouTube channel :)

Thank you for leaving such great lectures for free for junior developers.

It's really cool!!

Even though it's a free lecture, the lecture preparation and progress are really neat and easy to understand! Thank you! I also subscribed to YouTube! ㅎㅎ

Thank you for the detailed and clear explanation!

I lacked basic knowledge of SQL, and this helped me a lot.
