The lecture is a lecture, but as a job seeker, the words you said in Section 12 really touched me and comforted me. Thank you for your kind words. I think I asked a similar question in the DB1 course review, but I'm going to organize and apply the contents I've taken from the introduction to DB2 through a toy project. If I do a project, would it be better to complete the JPA roadmap or advanced course? Or would it be better to organize a little through the project and then proceed to the next course? (I've purchased all the courses.) Thank you.
