Opiniones y comentarios de aprendices correspondientes a Databases and SQL for Data Science with Python por parte de IBM

The beginning started simple enough to follow. The learning curve jumps from 0 to 100 in a short time. Not an ideal intro course. The labs are much more complex than what is taught. Instructions how to restart and operate a Run a new SQL was not shown and I had to spend lots of time trying to figure it out on my own. The powerpoints and information are easy to follow but the ease of use through IBM's platform is not friendly. Definitely easier places to learn as I have taken other courses online for intro SQL. I wouldn't recommend purchasing this. I'd either use it in a Free Trial or Audit it. For that value, you can spend your money elsewhere.

1. Lots of the slides have repetitive content, for Ex. different type of joins, Every slide have some repeating lines/audio. Could have taken some different use case or else could have combined it making it a single slide for each joins.

2. The "Table Loading Issue" its been a week now I am facing this issue, even have posted in the forum, the solution provided is also not working. Every time I try loading the table in db2 it fails, without giving any error/warning message. I am almost done except a few assignments and final peer graded assignment due to this I am not able to complete my course.

I did not find the course structure, contents, way of teaching at all good.

I spent more time figuring out how to upload data on IBM DB2 storage than practising. I feel in this course coursera must look into ways to make it more learnable, I seriously will say, I was unable to learn anything from this course I had to spend alot of time on google and other learning websites to figure out how to code in SQL.

In many assignments I just had to skip them because connecting to IBM is very stressful and difficult thats why I was mostly able not to connect with it.

The main reason for my low rating is the following:

1. The endless issues with the db2 console - an absolute nightmare to work with if you are not in the USA. Horrible experience. This slowed my progress down significantly to the point where I no longer wanted to carry on with this course

2.Not enough practical examples - as a result when doing the assignment, you want to tear out your hair. By my estimate, the Assignment should take no more than an hour if you have worked through everything.

Nice content, but lot of struggles with the tools. Watson studio has updated/changed the layout since the course was created, the content and description of the tasks in many cases don't live up to the real life situation. That's very frustrating, and you can see lots of people experience it if you check the weekly discussion forum. If the tool worked better (and if it would be better descried, as for somebody who never worked in Watson studio before) it would have been 5 stars.

I don't think the peer graded assignment is reviewed objectively based on the rubrics. The reviewer did not leave any comments about my "wrong" answers. I can not find where I did wrong as I already included the required clause in the query statements and got the right results. This is somehow disappointing. Even though I passed the course, but I got a lower score than I expected. I did not get any information about my "wrong" answer.

Lab was down for the entire time and it was really difficult to talk to someone and resolve the problem on time. It took 2 weeks for me to finish the final assignment due to lab issue. It was just waste of time any money spent on subscription. Coursera team said its 3rd party issue and they cant really help. IBM team was not providing the required solution on time. I got help from fellow students from the Forum and from google.

So many of the labs contain out of date or broken code, or simply don't work. The course also doesn't explain things properly and requires learners to make massive leaps in understanding and logic with little support. I had to get a friend to help me even get the labs to run, and then explain the content to me.

The only good thing is that I now have a basic understanding of db2 SQL - hence the two stars.

Too complicated to debug about the IBM tools, Its took me a tone of time just wandering to check password and username and too many errors without any solutions. I quite all the course not because I could not understand the content or could not do the exercises or lab, just because of the IBM tool too annoying, complicated and the instructions are out of date, also not details.

I am so far into this program that I can't turn back but level of instruction is ridiculous .. I'm learning more from YouTube than from the actually course the incomplete instruction and explanations are frustrating. Add to it the CONSTANT system issues, they are a distraction and they waste precious time. There is no way this course doesn't require prior knowledge.

it would be more helpful if the resources provided actually worked when needed. Nothing is more frustrating than following the lab instructions and not being able to complete it because the downloaded data wont load into db2. Forget trying to get timely help. That doesn't seem to be a priority for the 'education'.

Not great -- mix of SQL and Python that doesn't do enough SQL. I learned a lot of Python just to make simple database connections and run SQL queries -- it doesn't do justice to Python and isn't very helpful to learn SQL that way. The course would be better with just more SQL, and probably not in IBM cloud services.

Instructions and Labs were outdated, and the course material didn't accurately reflect the current tools. Professor assistance was also poor, having to wait numerous days just for a simple response. Dealt with the most technical errors during this class. Also, ran into issues regarding loading the DB2 instance.

Very hard to complete. Using the IBM Db2 service has horrendous. Because of the constant errors in using this service, it was a very jagged learning experience. I spent more time trying to find help from the staff on how to stop receiving open console errors than actually learning.

Strange tasks with errors, long waiting time for review, very bad support in the forum.

When you do week 6 will not change anything, the acquired knowledge will not be marked anywhere. Support says there would be a yellow banner "with honors", but I still had it after week 5.

the instructions weren't very clear and the assignments weren't challenging but they were really tedious. I stopped part way through the peer graded assignment simply because the questions annoyed me more than challenged me. IBM can do much better than this.

Would have rated it much better IF the professors / instructors did more to update the labs and coursework, spent way too much time figured out errors and reading forums, when this all could have been avoided if the instructors were proactive

Pretty terrible quality labs, barely explaining the material on connections or using SQL in python. No one can progress in the course because of some kind of error. It's been weeks according to the backlogs on the discussion forums.

The sql is easy, but the course makes it complicated for no reason. Instructions are incomplete on assignments, and issues are known to teaching staff. Ends up wasting 3 hours of time trying to solve known course issues.

Need to update instructions and screenshots for the ibm cloud site. Instructors dont respond to many questions in the forum and when they do their answers are often breif and vague

There were a lot of troubleshooting errors that I realise, were not only unique to me. These errors were not addressed properly and I ended googling some of these Issues

The course has big technical issues that slow down the completion. I am quite disappointed by the application utilized in the course. The course lessons are good.

Course content is great but working on IBM DB2 is very confusing. Faced a lot of technical issues where it took a lot of time to deal with.

T​he quality of the course material, workshops, and support for this class was abysmal compared to the other classes in this series

It has many technical issues with IBM Cloud. I couldn't focus on SQL skills from solving IBM connection problems.
