At first, I took the course because of the excellent curriculum for configuring TCP servers, so I had no intention of making a game server, but since all the examples are game-friendly, it is a course that makes me want to develop games without realizing it! As I listened to it, I even wanted to take the DirectX course when I had free time! However, the DB part is a course that proceeds through ODBC, and although I could do it if I was told to, I gave up because I hated it so much! ㅎㅎㅎ It was harder than LockfreeQ, which is a high-difficulty course... As someone who started with ORM, I really hate going down to the ODBC levelㅜ I have a physiological rejection reaction..ㅠ If I really need it, I will come back and listen, but for now, I plan to give up on DB and use TCP server like a message queue. Overall, I was very satisfied with the curriculum after listening to all of it except DB. However, the course itself is quite difficult, so I think you will have to keep reviewing it after listening to it once to make big progress!
