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.

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Any screenshot referring to ibm cloud is clearly outdated as it does not match with the current website.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.

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.

I actually liked this course. It introduces you to all the basic SQL commands (select, aggregate functions (min, max, sum, avg), joins etc). The labs enable you to create tables in the DB2 database (=the IBM database) and query them from a Jupyter Notebook. I have my own Jupyter Notebook installed , however, you can run and practice queries on the IBM environment as well. Then I liked that in the final assignment in week 5, the last problem 7 was a bit challenging ( I spent some 2 hours on this problem alone! searching the internet and the course forum. As a result, I did memorise how the INNER JOIN command works!!). The rest of the problems really had the same simple commands as in the labs. Finally, I received a helpful response from Rav Ahuja, the tutor of this course, the following day after I posted my question. I liked that rather than giving me a ready command, he pointed me to a general solution to this problem (in case I encounter the same problem again). Overall, I'm impressed with this course.
Hint: please save your log in credentials and the link to Dashboard-IBM Cloud from Lab1/week 1, you'll need to use them many times in other labs and the final assignment!

Though compact, the course doesn't seem to miss out anything on Databases and SQL as far as a new programmer like me is concerned. The instructor is awesome and so are the videos, readings and labs. Nowhere you would feel that prior experience with programming is a must to assimilate the concepts taught in the course.
Programming is a hurdle for many who aspire to be a Data Scientist. So this course would definitely provide a solid ground to people new to programming but gritty enough to be a Data Scientist and would help them in realizing their dream. The course is well desined, and specially well taught and the team would have really broken a sweat to make this course what it is. Loved it!

This course is very helpful to learn SQL fundamentals and to implement it in IBM cloud platform.
I am belonging to a poor family and i was very much interested to learn database management system and Coursera provided me the perfect platform to learn Databases and SQL for Data Science.
I would recommend all of you people who is interested to learn SQL to start with this course because it provide depth fundamental of SQL.
Thank you for providing an perfect platform to learn SQL.

I had never worked in SQL, so this course definitely provided me a good grounding on database handling. I do not have too much experience with pandas library of python, and this course provided me some hints on deepening my understanding in pandas, and the logical connection between pandas and SQL. It was also good to see the techniques which can be applied in Jupyter notebook or in python code itself to use SQL commands.

For someone who had learnt SQL back in High School, this course provided me valuable information on some of the more advanced topics and gave an insight of working with real world databases.The basics are taught from scratch and the use of database on cloud made the learning more simpler.So if you want to learn about data science i'd recommend this course and also to those who have some basic knowledge.
