DB Design Introduction/Practice That Even Non-Majors Can Understand

Each lecture was short, and I was able to concentrate and listen well because it only taught the key points. I'm so touched that even I, who can't finish the course every time, was able to finish it in 3 days.. DB design has always felt like an ambiguous area, but this lecture scratched the itchy parts exactly. Thank you for teaching so easily. I'll practice a lot on my own while listening to the lecture!!!!! (P.S. If you release beginner, intermediate, and advanced lectures, I definitely want to take them!!!!..!)

First, like other classes, the instructor explains things in an easy-to-understand way. When I listen and think a little bit outside the box, thinking, ‘So, is it like this?’ the instructor points out that part as well, which I thought was a delicate class. I was especially impressed by the requirements expressed in writing and the UI-based requirements materials. Since there were reference materials, I was more motivated to try it out myself and was able to concentrate better. When I designed a database myself based on the requirements, it took a long time at first, but as I continued the next practice, I saw myself getting better and better, so I studied really happily. As the instructor said at the end, I think I can try more practices myself by referring to other services and the erd site. If I have any questions while trying it out, I will leave them. Thank you for the great class!

This was a very useful lecture. I am starting a double major and taking a database class. The group project was not about building or distributing an app, but we had to select a topic and design a table. I was studying hard because I didn't want to be a bother, but I felt burdened. Then, this lecture alarm came like fate... I think I can do the group project well without being a bother for the price of a meal with a student discount!!! I will edit the course review after the group project is over. ㅎㅎ Good points of this lecture!! 1. It gives great tips on understanding the relationship between tables that I couldn't hear in school lectures. I understood it after hearing the explanation at school, but the method of understanding the relationship that this lecture teaches is much clearer. 2. It was good to do the practice together. After taking the class once at school and listening to this lecture, I stopped the lecture and tried it alone, and almost all of them were correct. I was so proud. There were some mistakes, but I understood everything after hearing the explanation!! 3. It is so clear because the table design method is specified with rules 1~6. 4. It gives direction for future learning. But one thing that came to my mind is that since I'm just starting out, I haven't studied Spring or Node yet... I don't know much about either of them, so I was wondering whether JPA is used a lot or Node is used a lot in the field/which one is recommended to study/how are they different? ㅎㅎ

I was vague about DB design and lacked knowledge, but after listening to the lecture, it was explained so easily, and after learning this way, I think I used to think it was too difficult. This is already my third lecture by JSCODE Jaesung. He always selects and teaches only the essential things that are frequently used, so I can learn without being stressed by too many things to learn. Thank you for the great lecture!

If I had been exposed to it 2 years earlier,,, Since I have been operating in the field for a long time, I was able to do the functions of small modules, but when designing the entire system DB, I was not sure because I did it by feeling. So when I was coding, I had a lot of concerns about whether the business or data structure was right or whether the data was aligned with the system. At that time, I watched more than 2 design-related books and video lectures, but I knew the theory, but when it came to designing, I had a hard time getting started. In the end, I handed over the design to someone else, but it wasn't much different. I experienced that if the DB design is weak, the service itself can be unstable. I've taken about 40% of the course, but I think I can do really well after I finish it. It's really a one-on-one tutoring. I'll try to sign up for other courses...

I took the teacher's MySQL lecture and then the DB design lecture. The learning effect is excellent compared to the lecture time, and it is explained so easily without difficult terms or concepts that it makes me wonder if it was this easy. Thank you for explaining it so easily. This lecture is helpful for both non-majors and majors. I will practice with the 6 rules as the teacher taught me until I get good at it!!!

It explains the essential parts of DB design in an easy and sequential manner. If you are new to DB design, I think it would be an efficient way to learn to complete this course first and study more theoretical and detailed parts. I had to study DB design urgently, so I was looking for a course that could be applied quickly and efficiently to my work, and I found the perfect course and finished it. Thank you.

This is a passing FE.. I've been studying and learning about backend recently (I've been studying it for over a year)... I've purchased quite a few related lectures, and I think this was the best and most efficient lecture method.
