Amazing course for beginners! The entire course is well structured and has good hands-on assignments. SQL is extremely essential for Database management and fun learning so please do try this one out!
A very useful course with some very interesting datasets/Jupyter notebooks to work through/practice your skills. Offers a good balanced blend between theory and practical/practice. Very good course!

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.

I think the course needs a bit more structure and written labs, some of them just tells you to practice what you´ve seen on the videos but I think it would be much more effective if there were more labs with specific problems to solve.
Also in some of the labs some solutions are given without explanations and those havent been even mentioned on the videos or the readings
The forum is not as effective as the previous course I did of this specialization, teaching staff takes ages to answer, and also answers are not satisfactory.
Anyway, the content is interesting and I have enjoyed learning

Decent course for an introduction to SQL. Basic commands were introduced well and the Jupyter integration was great for practice.
But the course was a little too basic; could have had more application-oriented content and a steeper difficulty curve. In addition, the Analyzing data with Python video from week 3 had about 1 one minute of voiceover that was completely unrelated to SQL or databases. The voiceover was just about Sodium in Nutrition. Felt very unnecessary.

This is a shallow introduction to SQL. Python API is shown, but not used in the assignments. The videos are OK at best, and many times, the examples are not the best, in that they don't really show why one would use, say, a left join instead of full join operation in real life. The earlier weeks need more exercices. However, the final week is quite good. At least the exercices and final quiz makes you think a little.
