Pretty polished

It was Great

Course information is uot of date and needs to be updated. One example: a question on the final test: >> When creating a foreign key, how can you define an action to take if a parent table row is updated? Use the ALTER TABLE command Use the ON DELETE CASCADE clause Use the rule clause ("correct answer") Use the CREATE TABLE command But actual: In PostgreSQL, rules are generally considered deprecated in favor of triggers for most use cases, particularly for handling updates to views and data modifications. While the rule system is still functional, triggers offer simpler semantics and are less prone to unexpected behavior, especially with volatile functions or complex queries.

Content is good. Probably too much focus on DB2 but that is to be expected from IBM. But the lab service is sometimes unusably slow. You may not be able to finish the final project, as on some days, the labs never load... You can follow along to an extent on mariadb or something on your own computer or server but the labs just don't load on the weekend. If the content looks good to you, go ahead and watch the videos, but don't expect to be able to finish the certificate because the labs might just be down.

The course is good, but some of the labs can be extremely frustrating. I understand the designers cannot be responsible for all user configurations, but I would highly suggest that lab content have more troubleshooting comments directly in the lab instead of only in the discussion forum, particularly around options for getting data into and out of the lab environment.

Subjects were made very clear but some explanations lacked information; e.g. when talking about indexing: the topic is way deeper than it was taught. I had to do tons of extra reading to be confident with RDBMS. I know this is what I am supposed to do, but I expected just a little bit more from the videos.

Nonetheless, it is a very professional course. Congrats!

The course is a great introduction to SQL but have some critical flaws: - Promote bad practices in some lessons (use lowercase in SQL statements and saturate queries in one liners) - Some quizes evaluate correct answers as wrong and even doesn't have a correct answer.

Il corso è ottimo, i laboratori hanno dei tempi troppo ridotti per poter lavorare spensieratamente

it's better if you also provide a guide on how to install mysql and postgre SQL

Good content on database principles. Exercises and projects are too easy.

SHOULD HAVE BEEN WITH MORE DETAILED VIDEO DEMONSTRATIONS/EXPLANATION

Some help but lacks pedagogical skill in its design.

Labs in Module 2 are not working properly.

This is just a very basic material.

Resources are inaccessible.

good

Of the five courses I've completed in IBM's Professional Certificate in Data Engineering, this one has been by far the most disappointing. I'm extremely frustrated with the excessive product placement, particularly for your cloud offerings. I enrolled in this course to learn about relational databases, not to hear a sales pitch about your database management system. While I understand the need to promote your products, I believe it should be done in a more subtle and integrated manner, rather than dedicating entire sections of the course to product demonstrations. Additionally, I've had significant issues with your Db2 on Cloud service, including being unable to create a simple table. Despite numerous support requests, I haven't received any adequate assistance from course moderators, Cognitive Class support, or the IBM Cloud support team. It's disappointing to see a company promote a product that doesn't live up to its claims. Learner time is valuable, and it shouldn't be wasted on learning about a subpar product like Db2.

Only few things are working right in the lab. I would not recommend it. Also, the explanation of the thread is nonexistent, you have to search it elsewhere. Yet I still learned something.

it was hard and overwhelming, to much info related different field like data engineering

Problems with Lab environments. Slow / poor support.

booring

Useless course, AI grading doesn't grade my submissions at all. Not able to switch to peer review as well. Worst service by Coursera. Not recommending anyone.

my peer graded assignment is showing failed but all the marks which has been given is full marks, then why is it showing so.

Poorly prepared materials, labs not loading, peer review is a lottery who gets to grader you...

Assignments were not good. Final project wasn't at a professional standard
