I learned quite a bit in this course, but it wasn't satisfying to me because a large part of the challenge was figuring out how to use all the tools through which the actual python and SQL instruction was delivered, the confusing organization of the modules, and the frustratingly vague instructions in the practices and exercises. If the intent was to demonstrate the range of platforms, tools, and access methods unique to them, good job. But if the intent was to actually learn coding skills in Python and SQL, in my opinion it falls short.

I think a better course would present 3 options: SQLite, MySQL, and DB2. Within each option, spend the minimum amount of time learning how to access the database, and then concentrate on some intensive exercises a little more challenging and "real world" than those we are actually given. Make a generous allowance of time for the course so those so inclined can indeed explore each platform and get even more practice with the actual problems.

The staff were fairly prompt in responding to questions, but many times they seem to either give the answer outright without explaining what a learner did not understand (which led them to ask the question in the first place), or they provide a response that does not really address the actual issue(s) exposed in the question. I think a different course structure might help with that as well, as it would be more easier for learners to preface their questions with the platform they are working from and the staff could more precisely intuit what the issue is.

Week 1 was fine, however I want to complain about the way teaching was handled for week 2.

I am a visual and kinaesthetic learner which means that i really struggle to absorb information audibly, this is fine as in ALL previous courses of the IBM professional certification there are videos supplemented by reading materials and guided labs (I can listen to the videos, and then work my way through the labs to gain understanding of the videos.)

In this course, specifically week two, you had the video, and a lab that had the instructions "do the functions stated in the previous two videos" TWICE.

This is, to pardon my language, total garbage. You are a teaching device who apparently has not bothered to attempt to teach anyone as you can't be bothered to write a brief PDF stating what you want us to do. instead assuming that we will do all the work regardless of whether it's helping our learning or not. I am sure this works fine for some people, for plenty of others it does not.

I'm rating this as all my previous IBM data science courses were very nicely made and acommodated all learning types.I think it's a crying shame that one week has been allowed to be so much worse than the overall level of the course.

This was probably the worst course I have ever taken on coursera. Unless you have at least some basic SQL experience, DO NOT take this course. And if you are in the specialisation which requires this course, do some basic SQL from somewhere else and then come to this course. There are a lot of problems with the datasets when you try to load them into the SQL database server in IBM DB2 and most importantly, the video explanations are too hard to understand. They explain most of the things which aren't really important and don't explain things that really DO have some importance. I'm pretty good at SQL myself (said by my cousin an SQL Database Manager for over 5 years) but I still struggled a lot with problem 8, 9 and 10 of the final assignment. Any moderators seeing this, when it is possible, I beg of you, please fix this course. If I hadn't faced any of these problems, this would be a very fun and interesting course. So what happened here? Everything is explained to us like we have mastered the fundamentals already and are coming back for a revision. Truly very disappointed with this course.
