Отзывы учащихся о курсе Databases and SQL for Data Science with Python от партнера IBM

needed to update many topics

hard to use sql server

not well designed

very simple

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.

Lab are the most frustrating. these are the place from where we as student get hands on experience but these instruction and IBM software platform doesn't work smoothly. We had to work on IBM based software platform such as IBN database(Ibm db2), Watson studio. I had issue in ibm bd2 software platforms loading tables and creating new credentials and could not fix that issue for several days finally gave up IBM Data Science course in "Databases and SQL for Data Science with Python". Not recommended, hope you don't get frustrated at the middle of the course

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.

Cannot progress through the course, because it needs access to IBM Db2 cloud service, but after following the instructions, I still get several errors. This is apparently a common issue, as posted on the message board.

The whole use of IBM platforms is troublesome in the whole data science ibm certificate.

At first, Datasette wasn't working; then IBM DB 2 was giving errors after an "ALTER TABLE" query; for the last, SQL Magic wasn't set correctly. This course was a mess. In discussion forums, I have seen people falling behind from their shcedules because of these errors, and there were barely answers.

W​eek 4 Labs do not work properly even though this has been a known issue for months. Connection issues. Typos in labs. Why Coursera continues to let IBM courses to be hosted on their website, I will not figure out. These courses need to be removed until IBM resolves these issues.

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!

Finishing the assignment on IBM DB2 is like a lottery, you need to really react quickly because you never know how long DB2 can hold on before next connection error. Thank you IBM, I now know which product I will not use in the future for data projects.

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!

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

There were connection issues with the labs for many users in my course. We couldn't access the course for a full weekend and the instructors did not respond to any messages for 2 days.

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

Tools used like Database console and Jupyter notebook used also crashes repeatedly. Course just gives very brief introduction to SQL, not much solid content.

Dear mentors, I'm sorry that I was unable to use Db2 in IBM cloud so I couldn't do the hands-on lab. Hope to have solutions from you. Thanks.

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

The worst course I have ever taken. I have no idea what course intended to teach. I would recommend not to take this course.

Instructions not working, need to rely on forums for alternative solutions
