Gaining some comprehensive view of online e-learning is so valuable to someone like me, not only need a project to present but also wondering about how to actually use sql, tableau in real scenario. For me personally, the course would even be better if the speed can slow down a little bit when draging object or click on some items in tableau. Some functions like fix() may need further explaination to really understand. Nontheless, I'm appreciate to your great project, Elitsa. Thank you!
