This is a really good lecture. Following the first part, I was able to follow the second part without a single hitch, and the easy-to-understand explanations made using JPA fun, like playing a game. The tips you learn while listening to the lecture are also a very good option. I'm planning to use JPA for a new project this time, and I'm sure I would have wasted a lot of time and energy if I hadn't listened to this lecture. On the contrary, I'd like to say that I'm really grateful to the instructor for allowing me to use my enormous time and energy in a better place. I'm the type that learns by applying rather than learning first and applying, so I'm planning to learn the basics after learning Spring Boot Utilization 1 and 2, and I'm already looking forward to it. I hope that others will also listen to this lecture and have more fun developing in the future.
