This is my first time taking a solid Inflearn course! It's not easy for beginners to imagine what the table will look like when they're put together, but I think my understanding of table structures has really improved while listening to Hongpak's course. I thought I was going to faint when I used the last three joins... but I think I'll be able to use things like this later on, right? Haha. Thanks to you, I learned a lot! Thank you! (ps. Please open a Python data analysis course too. I'll spend money..)
