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 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.

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.

Labs are always down and time out so you are unable to practice what you are learning.... Very frustrating!

There were several problems with the labs for several days, and the staff didn't offer any solution.

Boring course. Not application based. No learning by doing.
Boring and monoton lectures.

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!

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.

This course from IBM does a great job bringing all the basics of SQL and concepts around Relational Databases.
And since this is from IBM, which offers Cloud Computing services, the course involves some simple basics of using Cloud services to create databases and interact with them.
Relational Database Concepts
Basic Python code
All of these are all helpful from this course.

Best class so far in the IBM Data Science Cert program. Well done and really get to working with SQL for data science usage. Has a good intro on SQL and the essentials commands you'll need and then dives into working with datasets and writing SQL statements. Good pacing and the lectures get to the heart of each topic. Labs do a great job of following up on that. Make more classes like this one.

For a beginner it is an excellent course. Step by step hands on examples help one to negotiate and learn patiently. Now I have much better understanding of why DBMS is so critical and how one has to use the cloud DBMS remotely. How the tables are created and the significance of Primary and Secondary key. How the queries are run. How to do the joins to handle data from multiple tables.

Its a very good course. It has both video lectures & hands on Lab simultaneously make learning effective & boosts confidence of a learner. Some issues with lab like unavailability of them due to technical issues makes thing somewhat inconvenient. But coming to learning, course is very good. I would like to thank the instructor & coursera also to provide such opportunity for students.
