course was designed good. but i would advised to have a bit of Sql knowldge from youtube so that you will be able to understand everything much better.

A nice course for introduction with SQL but they could have used the software currently used in the industry like oracle's MySQL or SQL server.

Would have been better if there was a chapter on connecting to an sql server from an application or gui.

I wish there was a practical piece to practice after every video to help learn each new new skill.

Great course with great learning and an opportunity to apply that learning

Good for beginners

best courses

This is really a good basic knowledge course. Actually the more usable commands will be convered

As an already comfortable SQL pro looking to add a few badges to my belt, I went into this with an intermediate understanding. I found the course actually challenging, which on one hand was fantastic, but the monotone, stepping over every sentence, and flavorless videos ran by the same instructor, made this class very indigestible. Truly, I feel horrible for any non-English speakers who had to handle this course as first time learners. I'd be scratching my head, or running for the hills. I know the University of California has enough time, energy, and funds to put a good course together - so I'd lightly give this recommendation: find a speaker for your videos who can show emotion, deliver a speech, and knows how to teach a point. Maybe one that doesn't sound like they are reading from a teleprompter, and can deliver punctuation. It felt like one long sentence every video, no breaths taken. You made this course unnecessarily difficult with the speaker alone. Going right into the modules / quizzes that require specifically tailored, distinctly created queries done all by the user - you need to balance this course with at least an easy to understand instructor. This was not the case and I honestly wish I'd known that prior to signing up.

Not a great course, definitely not for beginners. This course was unfortunately very poorly structured. The instructor assumed that the learner had a lot of background knowledge, did not show things as she went, and overall was not very articulate. I needed a lot of external help from other resources and people to pass this. My partner is a software engineer, and even he was confused by a lot of this when I asked him for help and he needed to show me separately. This class might be helpful for expanding knowledge of someone who was already a data scientist, but not for beginners after module 1. More generally, it would be really helpful to have more frequent opportunities to try what was being taught. Only being able to try and write a query after an hour of videos of different topics was not a recipe for success.

Although the information and topics in itself are interesting and the course gives a good overview, the individual videos have a lot of repetition (in 5 minutes an intro, the main part and a summary), and I find the person who gives the course hard to listen to, as it often seems like she doesn't understand what she is saying. Also the questioning in the case study is very unclear - watching the discussion forum I'm not the only one who struggled to understand what they want. The provided answers for reviewing your peers are so widely interpretable that I myself got max points from 2 students for 1 question, while the third gave 0 points. And that for several of the questions. Overall not satisfied over the quality of this course

I didn't learn anything other than basic theories and basic practice, which leads me to have another better course from another platform ofc.! I am more angry to Coursera, as it took money automatically, without even emailing me or any other information before taking that money. I had finished the course and they took money twice. they didnt inform that i have to cancel the course even after finishing! why would they? ! this is using people, nothing else. Just WASTED my time and money. that's all.

Firstly, this course assumes previous knowledge of data science and working with databases, as some of the key concepts are not explained. Secondly, it is poor at teaching correct syntax for most of the functions and commands. Numerous times I had to do my own search to find the correct syntax. Thirdly, some of the tutorials contain mistakes both in questions and in assumptions about the data. Not the best course I have taken on Coursera!

Lectures were stilted and repetitive, some of the exercises were poorly thought through and the peer-grading is a joke, with people grading me as having got questions correct, when having seen the answers I now know I got some questions wrong! Questions from peers went unanswered in the forums.

It stars strong, but on weeks 3-4 it lacks comprehensive examples and guidelines, and that makes you feel lost. Also, the final assignment is very hard, and it asks things in a non-comprehensive manner, which makes you spend a lot of time until you understand what they are asking you.

Considering how hands on learning a language like SQL can be, this course does a lot of info dumping about the theory all at once instead of embracing the practical approach. This makes the course a lot more taxing than it has to be.

The teacher has really good knowledge of SQL and I really respect her for that, but as someone who is not familiar with SQL finds it difficult to give quiz without any side by side practice of the topic

The instructor was clearly reading from a slide without paying a lot of attention to actually 'teaching'. A lot of grammatical errors and flow of sentences made that obvious.

The interface isn't good to write the codes, and during the lecture it would be great to write and perform the task rather than showing :)

First of all, there is a mistake in examples. I looked on the forum and saw that there were some other people stating this. They didn't bother to edit the 6-minute video. Second, She just reads from prompter. Rarely but she gets stuck while reading. Also, instead of standing still while reading, she sways like a child. It felt like, they are not professional and they don't taken us students seriously

Material was good, but the staff is why I'm giving 1 star. Finished the course and submitted my final assignment for peer review, it has been "in progress" for 4 weeks, this is not acceptable to delay learning progress. Staff should have a way to monitor the assignments time and resolve. We respect your time, please respect ours.

The instructor is hard to follow because of her communication skills. I have to rewatch the videos, and even then I am having a hard time keeping focus on the material because of how many speech errors the instructor makes. I've decided to drop this course and find something similar instead.

Be aware that for many students the sandbox that is necessary for completing the quizzes at the end of each leasson does not work. This is a known issue but so far the lecturer has not commented on this

Course is fast paced missing out explaining key concepts. I had to research a lot of 'basics'. Moreover, what I found that most of the questions are not asked properly.

This course only shows the syntax, but didn't teach how to write. I'm still very confuse about the syntax after taking this course. NOT RECOMMEND
