Hello, instructor, thank you so much for making such a great lecture. As a student currently taking the JAVA backend national training, I feel that I have been learning without even knowing the basics, and at the same time, I feel very fortunate to have come across such a hidden treasure-like lecture. These are the advantages that I felt from this lecture. 1. The installation process is not complicated. (This is because the e-government framework is used, so there is no complicated installation process for DB, Tomcat, etc., and you can proceed with the practice right away through simple settings. Of course, it is all included in the framework.) 2. It was good that the instructor organized the contents learned in the middle into an Excel file, so that I could review it as a reference. 3. As a student taking the national training, I learned the concepts one by one from the basics, and the explanations of the lectures were clear and very easy to understand. I would like to thank you again, and while reviewing the first part, I will continue to complete the second part!
