This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.
I thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

Great information, however, the site that host the datebase for the quizes is outdated and no longer supported.

The course is good in itself, but answers circulate on the internet, making the certificate not very meaningful.

there is a lot of questions about how the questions were asked, i highly recommend you do see the discussions

Not enough examples were shared.
Certain concepts were explained without telling their underlying basics.

There are few examples about every lesson, and may not have examples for some lessons

The course is overall very high in quality and I found it really useful. The teacher explains the concepts really well and the exercises are very good. I really found joy doing the final course assignment. However, I feel that I got tricked into paying one more month of subscription, seconds after I paid for another month, I did receive the course certificate. I submitted the peer graded assignment one week ago. My plan was to continue with the other courses in this specialisation but after my experience with this subscription/payment philosophy, I will not discontinue and look for other online platforms with a better customer experience for me. Thank you nonetheless for the high quality of this course, I am certain many learners find the material extremely helpful, as did I.

This course covers topics in passing and expects you to internalize that topic. If this is going to be the pace, there really should be slides to review.
Also, if you're going to have someone just read off a teleprompter, hire an actor. The jarring cadence of this lecturer, the frequent tripping over words, or finishing a sentence only to realize there are three more words, it's brutal.
There are a ton of mini-quizzes which is fine, but it also has a "check all the right answers" which is both wildly pedantic and in many instances neither provable nor educational. Most courses I take through Coursera offer the "10 questions at the end" feature which is less disruptive and the questions feel more substantive.

The first two weeks were easy to follow along with. Unfortunately after that the course was severely lacking. There were not good explanations of things and new things would be added in that hadn’t been covered. When you post questions the mentors aren’t much help and the students will try to answer if they can. There’s also no way to practice. I also would’ve found it nice to see the tables they were pulling their “examples” from. I had to use other resources to actually study and learn SQLite. I’m assuming the people who gave this course a high score are already familiar with SQLite and just wanted the certificate.

First thing the instructor said was this course is for beginners. I am a beginner so I signed up. There are so many references I did not understand, no step by step explanation of how to find the data required to pass the exams so ended up looking for answers on the forum. Only way I managed to get through the third week was because my husband new how to use python and he helped me find correct answers - which were different to the ones we were given.
New steps were brought in without any basic explanation, again an indication that prior knowledge is needed.
Awful and disheartening

Pretty useless course, especially for someone looking to audit (learn for free). Well I would be livid if I actually paid for this.
Without a text editor in the course, you are trying to learn SQL via slideshow basically. There is no way to learn SQL without practicing. I switched to Codecademy's SQL course as it's much better because of the the text editor. They teach you and you practice with actual syntax and commands rather than stupid quiz questions. I still use some of the videos to better understand some concepts but only after I practice/learn them in Codecademy.

This course really stinks. If you already know SQL and just need a certification, a course like this would be fine. But for complex subject matter like SQL, it needs to go Concept->Practice, rinse & repeat. Instead, it's Concept->Concept->Concept->Concept->Concept->Concept->Practice. Sadie, it's real shame. She lures you in week one thinking this is going to be doable, and by the end of week 2, the writing is on the wall. It's too bad because a good SQL course could do a lot of good in this environment and they clearly have the infrastructure to do it.

Didn't like it. Too simple content (could only bear it with speed>1.5). Too many errors in the videos. Peer review is stupid b/c the tasks were simple but time consuming. Some of the works I had to review were simply copies from the internet (I can tell b/c some solutions you can find on the web contain answers to questions which have been removed). Teacher, however, did a good job. Clear, easy to understand explanations.

The course does go through the relevant topics. But the assignments and moderator attention (and quality of responses) are well below standards compared to other coursera courses. I would not recommend paying for this course, but rather just audit it. This way you will still get the material, but you won't have to go through the really bad and frustrating assignments (unclear/ambiguous/wrong wording).

Videos are not helpful. Going over the concepts with some codes and hypothetical examples are not useful. It would be great if we see the codes run and some of the results. Also, explanations are inadequate. The notions are oversimplified and rushed through. I learned the topics by doing the assignments which are very good for self-learning but mostly not covered in the videos.
This class does not go into enough detail. The lectures are not particularly helpful. The final assignment is mislabeled in terms of time it will take which leads to poor time management. Some of the questions are also considerably more difficult and require skills not taught or practiced well enough during the class. I wish I had done a different class.

Worst MOOC I fell across on web. Lot's of bugs in the assessment, lot's of incompleteness, teacher does not go deep in subjects, ends with a peer review letting you no guarantee it will ever be review, certainly not within the Free Week. I feel like I lost a lot's more time then I should have for the content I learned, overall very frustrating experience.
By Vera C P•
It's so hard, not enough examples to refer to when doing quiz. You should provide a variety of examples prior, similar to what you will ask in the quizzes. For someone like me, new to coding, it's very hard to remember how to respond to similar questions by the examples. People need to get familiar with the examples first, then move on to something new.
By Noemi A•
To be honest, i don't think this is for beginners.
Many things you need to find our for yourself and as per today, i don't know which tool to use for doing the queries? How to make the tool go and take the data for the spread sheets? This is basic.. so now i know the queries but i don't know where to use it.... Did i miss something?

Interesting course, it made me remember some things I learnt in college. Final assignment is too bad, simple queries for getting the info we are being asked to look, repetitive code to be implemented, a lot of ambiguity in the description of some points. I would call this course "SQL for newbies", or "First approach to SQL".
