Most companies use JPA these days, so I took the course to use it for projects. I listened to the JPA curriculum in order, but I think the basic lecture is something that you really have to study beforehand to properly use JPA. I am listening to the basic lecture again while listening to the next lecture to review it. It was so good because it was easy to understand and really resonated with me because it was explained thoroughly one by one. Thank you so much for the great lecture!
