Why I created a database course

•••

"I wanted to create a database course that contains the fundamentals truly needed for practical work."

The heart of all services,
Database

Why is studying databases important?

The core of every service we create lies in the database.
The database is like the 'heart' that drives software.

In other words, it's the foundational technology for all applications for developers, and an essential skill that planners and analysts must know to understand and utilize data. To implement good products and services and make accurate decisions, databases are fundamental skills needed by all job functions.

⭐⭐⭐⭐⭐

I was often moved by the step-by-step sequences and materials that could only come from deep thinking from a beginner's perspective. Just as the current lectures have been for me, I hope you will continue to create lectures that can extend a helping hand to people who are lost and struggling like I was back then. Thank you!

"Spring Boot - Core Principles and Applications"
Course Reviews

⭐⭐⭐⭐⭐️

I only knew how to do CRUD, and when I occasionally encountered DB issues, even after googling, the knowledge was fragmented and seemed to have gaps somewhere, but this is a lecture that fills those gaps. ... I guess fundamentals are important after all. And I don't think there's anyone who can establish those fundamentals as well as Younghan-nim.

"Spring DB Part 1 - Core Principles of Data Access" Course Reviews

⭐⭐⭐⭐⭐

It's truly the best. While taking other courses, I had questions like "Why do they use it this way?" and all those unresolved doubts and questions I had while self-studying like "Why does this part work this way??" are all clearly explained. ... If you've had the experience of not being able to cleanly resolve your questions while studying alone, I really highly recommend this. I'm really looking forward to the intermediate and advanced courses too.

"Kim Younghan's Practical Java - Basic Edition"
Course Reviews

⭐⭐⭐⭐⭐

Showing how things actually work by keeping the web browser developer tools open throughout the lecture and demonstrating the actual operation was what made me think "Oh, so this is how the parts I'm actually studying work!" and became a catalyst for developing more interest. ... Please continue uploading many lectures and spreading positive influence to many people. Thank you for the lecture, I enjoyed listening to it. ^^

"HTTP Web Basics for All Developers" Course Reviews

⭐⭐⭐⭐⭐

I was truly grateful for the practical lectures and detailed explanations you provided, as well as your thoughtfulness in explaining previous topics once more. ... Due to the limitations of government-funded education, I couldn't collapse like this and found your lectures while searching, and I feel like my life is going to change thanks to them. With the goal of working at the same company as you as a developer, I will strive to become a competent developer. Thank you sincerely.

"Spring Core Principles - Basic Edition" Course Reviews

⭐⭐⭐⭐⭐

I was able to get a big picture of what I could build with Spring, and instead of just teaching the technology randomly, you naturally built it up from start to finish by showing how these technologies were introduced to solve inefficiencies or problems that arose while writing code, so I was able to learn smoothly and well!

        今回データベース講義をオープンされましたね〜 ヨンハンさんの講義を見ながら勉強して、今職場生活中です 働きながら感じたのは、dbはSqlも重要ですが、db自体についてよく知って活用することが重要だと感じたので、復習を兼ねて着実に勉強中です。 いつもよく学ばせていただいています〜
