Recently, while listening to JPA, Utilization 1 and 2, I thought that just using JPA would magically increase development productivity, but Spring Data JPA is more magical than JPA!!! After taking the JPA lecture, listening to the utilization part, and taking the Spring Data JPA lecture, I felt like I understood it better. In the past, I tried to start with Spring Data JPA without thinking, but if I had not taken JPA, it would have been really difficult. I am a college student who is about to start preparing for employment, and I always wait for Younghan's lectures. I am looking forward to the next lecture, querydsl, and I am also really looking forward to other Spring lectures and web lectures. I have bullets ready to buy them as soon as they are released!!! Thank you for always giving great lectures!
