I think it's good for those who are new to development. It's a lecture that will be very useful for those who are new to development because it doesn't cover difficult aggregate queries like join and lookup. The lecture language is Golang, so some people might not be familiar with it, but I think it focuses more on server structure and DB than on the language itself, so I don't think there will be much difficulty in terms of language. I personally took the course with satisfaction and learned a lot.
