I have already completed Spring Data JPA. I listened to the lecture while working, and Chuseok was the opportunity, so I took the time to listen to it all. When I listened to it a little bit every day, I kept forgetting what I had learned before and had to review it, so it was hard to make progress, but when I listened to it all at once, I remembered it well, so it was great!! Thank you for the great lecture. It helped me a lot in improving my skills. I hope you have a happy day today!!
