Because of the nature of my job, I use SQL every day, so I wasn't sure if there would be anything particularly new. However, I was impressed by how this short course managed to cover not only the basics but also topics like subqueries and transactions—which can be explained quite complexly depending on the person—in a concise way that hits all the key points. Even though the course was very affordable and didn't require a huge time commitment, I felt it was a rewarding experience because it packed in all the essential elements of SQL. The occasional insights from a practical, real-world perspective also made it a great experience. Thank you.
Hello Seungho Lee, Thank you so much for your thoughtful and in-depth review. I created this course with the goal of effectively delivering the core essentials of SQL within a short amount of time, and I am delighted to hear that my intention was well-received. It is especially rewarding to know that you found clarity in areas that can be conceptually confusing, such as subqueries and transactions. As you mentioned, this course focuses more on accurately understanding the core concepts that can be applied immediately in practice, rather than simply "knowing a lot." If it served as a helpful summary even for someone who already uses SQL frequently, that in itself is very meaningful. I hope this continues to be of even a small help to you in handling SQL more quickly and accurately in your professional work. Thank you once again for the great review!
