Kim Younghan's Practical Database Introduction - SQL First Steps for All IT Professionals (Step by Step from SQL)

Hello, Younghwan! I originally leave course reviews after watching all the lectures completely.. but since I'm recording all of your lecture content while taking classes, it seems like it would take too long, so I want to quickly express my gratitude that thanks to studying with your lectures for 1 year and 10 months, I was able to get hired as a new developer, so I'm leaving this review in the middle of taking the course..😊😊 The company I got hired at uses Kotlin + Spring for backend until this year, and will transition to TypeScript + NestJS in 2026, but thanks to the fundamentals and confidence built through your lectures, I feel like I can understand and handle any language or framework transition if I put in the effort. Thanks to the knowledge built from the ground up that I learned from your lectures, I was able to not give up on becoming a developer despite the difficult job market, I was able to do side projects with people I didn't know through trial and error, I was always in the top group at bootcamp and could grow together with skilled people to produce results, and although the company isn't a famous and excellent IT industry company, I was able to bear fruit despite it being a difficult time for employment. Just like you often said at the end of your lectures about "what's next" or at conferences and special lectures, even though I might not get many responses from the numerous companies I applied to, there existed a company somewhere that would hire me😆😆😆 With the mindset that this is truly the beginning, I will strive to become a developer who burns steadily for a long time rather than briefly flaring up! I'm so very grateful and always respect you! It will take time, but I'll complete both the beginner and basic courses bit by bit on weekends and see you again in the course reviews

You've opened a database course this time~ I'm currently working at a company after studying with Younghan's lectures. What I've realized while working is that while SQL is important for databases, it's crucial to understand and utilize the database itself well, so I'm studying step by step as a review. I'm always learning well~

The lecture quality is really good! Even though I already know all the content, I find myself listening to it again.. magic Thank you for the great lecture~

Hello, Younghwan. I'm a junior data engineer. While preparing for a job change and going through multiple interviews, I found myself reflecting on how I had been overconfident, thinking 'Oh, I already know these basic things.' I decided to go back to the beginning and solidify my foundation from the basics, which is why I started taking this course. Your final statement that 'databases are the most important' really resonated with me. Thank you always for the great lectures. I will definitely listen to all the remaining lectures and leave reviews. It's getting cold, so please take care of your health and may you be filled with only good things :)

Thank you for the great lecture!

It was helpful.

Thank you for the great lecture.

It was great that you explained it in an easy-to-understand way I was able to gain confidence by building a solid foundation I want to listen to the next lecture too!!
