First of all, I would like to thank Mr. Kim Young-han for creating such a neat and good lecture and sharing his knowledge. I purchased the lectures included in the roadmap at once during the last discount event and plan to study them slowly until next spring. I am currently a current developer preparing for a job change, and since I work at a company that does not use JPA, this is the first time I have encountered it through this lecture. This lecture was really helpful, and I will definitely achieve my goal and come back to leave a comment. Thank you!!
