It organizes the essential content needed in practice step by step, making it perfect for taking as a bootcamp-style course when first learning SQL! No matter how much AI technology advances, when you know nothing, it's natural to feel vague about where to start, but through this course, I definitely got a clear concept of 'what' to ask. I think the price is reasonable for this level, and I was able to get a sense of how to extract and process data in practice without any problems studying on my own. I especially recommend this to those who work in number-friendly positions but have been inconvenienced by only working with provided data~~

It was very helpful for reminding me of the entire SQL.
