Every time I looked at an execution plan, I found it difficult and didn't know how to interpret it, but through this lecture, I was able to clearly understand, thinking, "Ah! So that's what it is!" The terminology is well-organized, and the lecture serves as a great guide by explaining the approach and what needs to be done step-by-step.

Although most of the content was familiar to me as a 5-year developer, it was good to be able to clearly organize the theory The audio volume does fluctuate between lectures though

It seems like a lecture that can be put to practical use immediately.

I think it's really great that you explained in an easy-to-understand way how to optimize the index search. The only thing I'm disappointed about is that the course duration is 12 months 😭,😭 I wish you could let me take the course for life even if I have to pay more. :)
