I wanted to listen to DB Part 2 since the beginning of the Spring Roadmap, and I finally listened to it all! I was so happy to learn the testing method I was most curious about, and I was able to experience using JdbcTemplate, MyBatis, JPA, Spring Data JPA, QueryDSL, etc., and I was also able to learn about transaction propagation that I didn't learn properly in DB Part 1. I'm going to review DB Part 2 right away. When I first started the roadmap, I heard that Spring was very difficult, so I was a little worried even though I was just listening to the lecture. However, when I actually started, I couldn't say that Spring was easy, but it was content that even beginners could follow, so it was great. And as I listened to the lectures in the roadmap in order, I gradually got used to Spring, so I was able to understand the later lectures faster. Of course, since I studied a lot of content, I don't think I remembered everything. In the future, I will try to remember and learn it again by making something myself. It was also good that the community's Q&A was still active. There were many cases where other people had already asked questions about the questions I was going to ask, which helped me a lot in finding answers quickly. Also, the answers from Professor Kim Young-han and supporters were also continuously being helpful. I have purchased all of the JPA roadmaps, but I have been listening to the lectures so diligently that I don't know if I will listen to the next lecture soon or if I will take a break and listen later. When that happens, I will study hard again. Thank you for making such a great lecture!
