IBM DB2 database didn't give me good using experience.

Did not find this any helpful really bad programmed

Not suitable for non computers background students.

WHY FORCE ME USE THE IBM CLOUD? SO COMPLICATED

The IBM tools are so unfriendly to new users

Last few lessons are not clearly explained.

There are so much errors in notebooks!

I had difficulties wih IBM platform.

The voice-over makes me wanna sleep.

DB2 console is so difficult to use

The Lab env sometimes has trouble.

Expected more from an IBM course.

they didnot give you certificate

needed to update many topics

hard to use sql server

not well designed

good course

very simple

good

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.

Using sql magic is not a portable skill to workplace applications, so instruction and evaluation using it just means I'll have to relearn this topic with an IDE-agnostic method later.

Moreover, the db2 ibm connection library uses outdated python libraries - it fails unless you use the specific libraries that are supported - and these libraries are incompatible with the latest version of jupyterLab. The supported version of JupyterLab is never mentioned, so you can only use the online environment, and not recreate work on your local machine. This seriously damages the usefulness of the course materials. In addition, this course has many bugs and hasn't been updated. The most aggregious bug is not providing the chicago crime database script (until you reach module 6), as db2 Lite cannot parse a 7 million row CSV. In addition, none of the csv upload services worked properly - they had page faults, parsing bugs, warnings with no inserts, and mismatched datatypes all over the place. I ended up entering them all using hand-written sql-scripts, which is just busy work and not learning.

I would not recommend this course to anyone. They would do better reading a book on python database connections that is current, uses an IDE that you might use in a work setting (pycharm, sublime, notepad++), and doesn't omit the specific library version arrangements required to make the exercises work on any machine.

This was awful!

The main issue with this course is the tools that we have to use in order to complete assignments. Learning and understanding SQL was the simple part. What I struggled with most was using IBM's DB2. This course needs to be updated and explained thoroughly because the way I struggled with just trying to get the systems to work was unnecessary. I never been so frustrated over an assignment before and this left me very discouraged. If there are any fellow students that are reading this you will need a lot of patience with this course ad if this reaches any professors ir people in charge of this course I hope that you look into this issue immediately and update the course to make the instructions clearer and more concise.
