I've only listened to the beginning, but it doesn't seem to be what I expected. It seems like it just considers the contents in the table of contents keywords, and there's a lack of explanation on how to apply it or how to write a query to apply the contents well.

Hello, thank you for leaving a review. In fact, writing basic queries is quite easy. However, I think the difference between knowing and not knowing these basic theories is huge. This is because the more data there is, the more you can know these concepts and apply them in advance. I wanted to provide you with actual data, but since the data format varies depending on the service, I focused on the concepts I applied in practice. However, I'm so sorry that I didn't give you a good satisfaction. I will come back next time with a more useful lecture. Thank you for listening to the lecture!
