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.

•Hi,
I completed entire program and received the Professional Certificate. On the Coursera link of my certificate "3 weeks of study, 2-3 hours/week average per course" is written. This information is not correct at all, it takes approximately 3 times of that time on average! I informed Coursera about it but no correction was made. It should be corrected with "it takes approximately 19 hours study per course" or "Approx. 10 months to complete Suggested 4 hours/week for the Professional Certificate".
Here is the approximate duration for each course can be found one by one clicking the webpages of the courses in the professional certificate webpage: (*)
Course 1: approximately 9 hours to complete
Course 2: approximately 16 hours to complete
Course 3: approximately 9 hours to complete
Course 4: approximately 22 hours to complete
Course 5: approximately 14 hours to complete
Course 6: approximately 16 hours to complete
Course 7: approximately 16 hours to complete
Course 8: approximately 20 hours to complete
Course 9: approximately 47 hours to complete
This makes in total approximately 169 hours to complete the Professional Certificate. As there are 9 courses, each course takes approximately 19 hours (=169/9) to complete.

•all the proprietory IBM Watson and cloud services stuff just distracts from the meat of what I wanted out of the course series. It's not user friendly and required so many steps that had nothing to do with data it was far more frustrating than helpful. I hated every step of the first 5 courses. I'd really like my money back.

•The worst course I have ever done. All participants were confused in the final assignment and the instructions were very poorly organized. Lack of clarity and the instructions being very outdated and incorrect lead to thousands of annoyed and stressed students. Waste of time.

•Hi there, in my opinion this course in too short for a beginner and the logic behind the database and relational schema is not very clear. It looks like an instruction book for IBM user, I cannot feel the interaction with the interpreter. But thanks a lot anyway!

•This is very much focused on the IBM cloud. For someone who is not familiar with it will have to spend a considerable amount of time trying to find which is where. Course documents are outdated specifically on creating DBs on the IBM cloud.

•Google Simulating Environment has the bugs and when you writing to Support, this rich guys stat you to do a free "PROD" testing : no way, it's theirs bugs, and I have my own. What the hell are paid for?
Shame on YOU IBM for such solution!

•If you do not have prior knowledge of DB2 and IBM Watson this course is not for you! The instruction to connect the two programs to complete the final project are inadequate at best. Would not recommend this course!
创建者 Facundo O
•Not a course for beginners. It advances way too fast and the topics are not explained thoroughly as to truly understand them from a beginner standpoint. Would suggest looking for another course...

•The loading data to database and using the database for peer review task took me several days. It was very anoying task. I dealt with time consuming manual jobs rather than wiring codes
创建者 Vivek R N
•Its only about how to connect to IBM DB2. I got stressed out trying to work on the IBM platform. Working on platforms like My SQL is so much smooth when compared to this
创建者 Utsav
•Tools used like Database console and Jupyter notebook used also crashes repeatedly. Course just gives very brief introduction to SQL, not much solid content.

•Everyone in this course has problems with IBM Cloud credentials. Staff gives everyone the same generic response and provides no real help.

•Sadly, this is the most confusing and error riddled course among all of the courses on coursera.
创建者 Adi B
•Awful course, with very hard to understand assignments and instructions. Would NOT recommend.
