This is Younghan's lecture that I always trust and listen to. The beginning of the lecture always seems to be a mixture of excitement and worry. Even though I really want to learn and want to take the lecture, I get scared when I see the table of contents and the time required to complete the course. However, I really feel that Younghan's lecture structure is well-organized and that he always thinks about how students can follow along well and how students can learn and use this technology well! In particular, the explanations in the lecture notes make me promise to study even harder. Thanks to that, I was able to complete the DB Access Part 1 and Part 2 with great enjoyment. I am so grateful that you created such a great lecture that I can become a better developer once again. You worked really hard.
