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.

If you are located outside USA or Canada, don't take this course.
Because IBM cloud DB2 will not give you free account to do the lab exercises. Otherwise you have to pay 202$ to get an account.
I didn't continued the course due to this issue.

This course is more about IBM roping you into using a bloated cloud ecosystem, than it is about teaching you SQL. You will only learn DB2 stuff, and only through their cloud dashboard. This entire specialization is disappointing, but if you've made it this far, masochism may carry you through it.

The course teaches SQL quite well. But it doesn't teach and make practice about the connection to a database and use of sql magic. Hence, its very frustrating to understand the significance of '%sql' in a Final Assignment review. I think a lot of students are facing the same problem.
Hence, it feels like- Final assignment is to check whether we can connect to the database, rather than checking our subject knowledge on SQL.

I would've given a five-star rating gladly, if it weren't for the terrible user experience of IBM DB2 Console, which wasted 4 hours of my time trying to load three small csv files into database tables.
Apart from this "blocker bug", the course is well-organized and worth the price.

Only one star and I think it does not deserve it. On week 3 the assignment ask you to establish a connection with database and because It gives me an error for more than 3 weeks, I decided to use Forums. After a couple of dozen messages requesting for help, I received only 2 answers from the professor:
First: "Go to week 3"
Second: " Idon't see any attachment"
I have sent so many screenshots that it is ridiculous. So If you find yourself unable to connect to the database and it gives you a constant error; my suggestion is PRAY!. Please, do not cry like me in desperation after a month. Just PRAY. I think it could work... someday

Horrible experience. The course is not updated. The ibm cloud function doesnt work at all. There are hardly any videos. Most of the content is just theory which you can read from anywhere. Dont waste your money.

I can't open Db2 console on the IBM cloud, it only showed 502 Bad Gateway. It cost me more time on finding another way to finish the homework.

No live examples, no tutorial on how to navigate Db2 cloud. Maybe I was expecting too much; disappointed.

Although the material was clear and concise, working with IBM Db2 Cloud was a headache due to its unresponsiveness

Basic SQL, course needs to be updated to reflect changes to IBM cloud (or better yet, don't use IBM cloud). You can find better courses on SQL on Coursera/other MOOC sites.

The IBM cloud "service" leaves much to be desired. Multiple times I've experienced outages while I was in the middle of lab assignments. It's a paid course where they give you "free" credits to do the course work in their cloud "service." But the credits are inadequate for the labs and they constantly ask for your credit card to buy more "service." While the class is okay I wouldn't recommend it to anyone because of the poor IBM cloud support.

This is a great review of an important topic. If I knew how much this mattered for the advanced capstone course I would have paid more attention. As it was, I came back here frequently.

This is definitely the best course so far on the IBM Data Science Professional Certificate! I have been very keen to learn about SQL and Relational Databases for a while and this course enabled me to achieve that objective, in a fun practical manner. I was challenged all the way through and cherished being able to spend time making mistakes and learning from those mistakes in the hands on lab environment.
10/10 course and if the author of this program ever decided to make another course extending from what was taught on this course, it's safe to say I will be the first to sign up!!

In case IBMER's fails to have DB console lite access, its difficult to complete the assessments, hence there should be other alternative to practice it.

This course teaches you the basics of SQL completely unrelated to Data Science. SQL is not mentioned in any further courses in the specialization. Could have very well skipped this course from the specialization. There was not even a single assignment that involved both SQL and Data Science.

No videos for week 2, sub-queries were confusing and questions 9 and 10 on final project are very 'vague' and 'confusing' with asking questions about Area(s) when in examples and previous course work we were taught to use group by, but correct answers did not use group by.

Practice lab assignments were excellent in reinforcing my learning, they were just the right kind of challenging. This course has been the best one in the Data Science Professional series by far.

One of the best course I completed on Coursera. All the learning material is well organised and easy to understand. Also the non-graded sections regarding relational databases are interesting.

Really right to the point and efficient. Good examples and short direct videos. I had no idea about SQL before and now I can run good queries and have enough tools to learn even more.

Overall good course but a few typos and unclear instructions, mostly with the labs and our own 'user specific" DB2 specs which were needed for the 1st and 2nd lab - yet, clear instructions for doing so were posted several labs afterward. Labeling of individual labs (their titles/ filenames, when opened in Jupyter notebooks, did not correspond with the actual weeks in the course that the should have - wks 2 were called wks 4 and wks 3 were called wks 6) That made it a bit confusing at times. They appear to have been from a different course or earlier revision. Maybe revisit and revise this course soon for better flow. Also, please check the comments/discussion boards and address those concerns that are repeatedly coming up. Quite a few more students than just myself were stumped or confused over the same issues. Thank you.

Worth all the effort..! Great coursework if you're willing to spend some time to understand DB2 infrastructure,creating Db2 database on IBM Cloud, compose and execute SQL queries, and access a database from Python based Jupyter notebooks. Key takeaways from the course : - Creating databases on IBM Cloud - Troubleshooting basic loading errors - Working closely on creating tables on real time IBM DB2 instances - Connecting to db instances using python and perform basic data summarization - Performing data loading through RestAPI's
