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!
The lessons were short and easy to follow, providing all the basics as well as a few more advanced topics, to get student quickly up-to-speed on databases and SQL and their application in D/S realm.

The information is made available, but it is just purely death by powerpoint with a scripted voiceover. There is zero intimate tutoring. This applies to all of the IBM Data Science professional certificate.
My advice on how to improve this course is to take a look at courses such as those in the Python for Everybody specialisation with Dr Charles "Chuck" Severance. When he teaches there are powerpoints, but he is intimately explaining what is happening, with the camera switching between him and his powerpoint which he is actively annotating and explaining. That is a much better teaching resource. With the IBM courses, not once have I even seen an image of the tutors or had any detailed explanation or evaluation from a human - it is purely a script describing a powerpoint slide throwing in as many meaningless business-speech words as possible, almost an advertisement for IBM services which I have the luxury of paying for.
The information is there and that is why I have not rated this as low as possible (there really are some dodgy courses out there!), and I will complete the professional certificate I paid for, but to me, this style of teaching is very impersonal and you really do feel like just a cash-cow for the company rather than a valued learner.

There were a lot of problems with the online tools needed for this curse. Staff members eventually responded and solved them, but because of it, I went over my time limit and had to pay another month's coursera fees. Seeing as this is an IBM course and the tools were from IBM, I was expecting a smoother experience

This course is a "Big MESS" to me. SQL they used is completely different. It doesn't accept the normal SQL statements. Column names are case sensitive and Writing the where clause gave me head-ace. It wouldn't accept the straight comparisons. Columns names should be expressed in quotes.I hate this course

People knowing some SQL will learn next to nothing. For complete beginners there is way too much emphasis on using the semi-unusable IBM cloud platform instead of learning SQL. The assignments are also too easy and short, which means you don't get to actually practice the bit of SQL you could learn.

If you know nothing about SQL, don't take this course since it just a brief introduction without any in-depth explanation. By no means, a beginner can understand what SQL is in this way. But if you've already known something about SQL, it's good for refreshing your knowledge.

This was over challenging because labs and lectures definitely lack decent level explanations to learn the content permanently. I can't say I learned nothing, but I can clearly say this is a below mediocre level of training.

1) Material and presentation was not engaging and structured
2) Final assignment in terms of administration (copy pastes and screenshots upload) was a pain in the ass
3) Not enough hands on exercises

A lot of the "optional" materials are actually quite important. UC Davis's SQL course is far superior to this one due to more access to coding practice assignments. I expected more from IBM.

I expected a more detailed explanation in templates. as it was done in the previous course (Python for Data Science and AI). since this database theme is done with many procedures

We spend more time debugging and googling to get things to work than the actual project time. The forum is full of this, but the IBM guys do nothing. This is putrid it tell you!

Would be awesome with a few corrections and updates to course materials- more concise and clear instructions would also be helpful for this beginner level course.

Any screenshot referring to ibm cloud is clearly outdated as it does not match with the current website. Instructions on how to get db2 connection credentials are MISSING and the ibm cloud website is not at all intuitive. There is no way to change the default uid/password for db2 connection and there are no instructions either in the ibm cloud site or in this course.
I just spent almost an hour trying to solve this problem but in vain. I should not be wasting time and resources trying to establish a stupid database connection.
For $39 plus tax per month this is not only disappointing but robbery!

The videos do not show the proper syntax (there are no ";" at the end of the queries) and pass over concepts quickly. They begin with "After watching this video, you will know how to do a, b, c, ..." and by the end of the video, I can't say I know any of the content presented.
The creation of the IBM account was complicated as there are many sets of instructions in different places on the course's page.
There was also a mistake in a hands-on lab (which I reported).
I would not recommend this course at all.

If I could I would rate this course 0/5
None of the resources you ARE OBLIGED TO USE to accomplish the course work. You have to use The console on IBM cloud for DB2 and does not work. You should install the desktop version of the software and it is somehow blocked by US export laws (what on earth should that mean?)
Why do not you provide alternative ways to do it?! That's just disappointing, to say the least.
Shame on the creators and people lucrating on this product.

This course is the lowest quality course of coursera. Credentials in final assigment don't come through. The instructions are poorly written, thank god I have before hand knowledge of ibm cloud. not a single course worked as it is intended. Total rip off of my money, since you can't check final assigment before subscribing to the course.

Lots of errors. To this course's credit, there was a lot of effort providing practice work in the early material. For the more difficult tasks at the end, there was far less structured practice work.
https://www.w3schools.com/sql/default.asp this link will come in extremely useful, as will supplementary YouTube videos..

This is a useless course. I've done many courses on Coursera without issues, but I would not recommend this one, mostly because you've got a zero chance of getting any response from anyone if you need clarification or assistance with anything, even completing assignments.

Die Videos sind veraltet und die Plattform von IBM hat sich mittlerweile stark geändert. Ebenfalls treten einige Fehler auf, das ablegen des finalen Testats war nicht möglich, da der Timestam im CSV "Chicago_Crime.." nicht erkannt wird..

Very limited to IBM DB2. Not useful in real world.
Very limited and restrictive practice and assinments.
For a true learning experience one needs to do a lot of external research and work to show a measureable benifit.

The tools used are not very user friendly, I spent more time troubleshooting them than actually learning. It feels like the instructions need to be reworked and ordered correctly.

This course doesn't work. It relies on IBM Cloud that will spit out an ERROR message with every command, even if you copy and paste from the course instructions. Save your money.

No clue how to find anything on IBM cloud for the last assignment. How can it be so hard to write clearly how something is done? You are changing money for this.

DB2 instance required in the course can not be created due to repeatable service issue and it naturally stops the following courses.

Poor explanation, lack of tasks and bad developing environment provided. I'm very disappointed with this course.
