This was a good lab (although not beginner-friendly) for using SQL. I think there should be more explanation on some exercises. For example, the 3rd challenge asks for "unique visit id". I know SQL enough to be familiar with CONCAT function, but there's nothing in this exercise that points to the use of this function, since I had no idea I was supposed to fuse two different IDs. I don't work with sales, and I don't know if this is common for this area or not, but I think there should be a fine print explaining what "unique visit id" is. If this was a real life situation, I'd probably ask my senior what each column stands for and what does this mean. Another example is conversion rate. I had a vague idea, but I don't think everyone that takes this course might know it. I had to look it up to understand what it meant. It's nice to propose an answer, but every time I came to check the answer I realized there was something in it that I couldn't possibly have known in factual terms (in SQL terms, everything was doable).
