I started dreaming again.. Thank you I was born in Tongyeong, grew up in Jinju, and also grew up in Tongyeong.. lol.. I'm a 32-year-old young man. Others ask me why I quit my job that pays well.. but I ended up quitting and wanted to become a developer, so I paid for the entire roadmap and am taking classes with Teacher Yeonghan. A hundred times hearing is better than seeing once. I wondered if this was possible while working as a management support and planner, and I feel like I can do the parts that I regret now myself, so I think I can become a good developer or planner. Thank you.. I'm working really hard for the remaining 6 months with government support. I'll make sure to become a good developer! Teacher Yeonghan, before learning Spring Database, I need to have basic DB knowledge. What is basic DB knowledge here? I want to study in advance, but I don't know what it is, so I'm leaving a question in the course review. Thank you..!! Always stay healthy
