I really enjoyed this course and felt it was excellent as a beginner course for someone who had very minimal knowledge of this skill at the start of this course. Some of the questions were a little confusing and the lectures could delve a little bit deeper into the SQL nuances to help develop a more complete knowledge of the subject. That being said, I would recommend this course to anyone who is interested in the world of SQL and developing their skills and getting resources to succeed.

Overall good introduction, can say that the explanations and teach were okay. Bad thing is the structure - at first you watch multiple videos about completley new topics to you (like 1h+ of video) and only then there is a hands on excercises, already after you have forgotten majority of what was explained. I feel that it would be much better to have tests right away after lectures on particular topic or some kind of code alongs.

But as I said initially - a solid beginners course.

The course has quite a lot of content, and all of it is relevant. The lectures in the initial weeks were really helpful. After the second week, it was difficult to keep up with the instructor. The practice challenges and additional resources were very helpful and added to my learning experience. The final assessments at the end of each week helped me learn a lot. The peer-reviewed assessment at the end was a challenge in itself. Overall, a good course for beginners.

As an introductory course on SQL goes, this covered everything I think I'd want to know on the subject. It was nice and short and contained just enough examples to get the material across. I am marking this course down a bit because I feel like a course like this isn't the best format to learn SQL. This course links to some external resources that cover many practice examples and problems that I feel are a much better method to become familiar with the topic.

Course was well structured, videos were efficient and informative, very well done! I do think the course was light on the Data Science part of the equation, and found it odd that the final question on the final exam asked you do considering doing predictions or segmentations when none of that had been covered in the course. Would be better to add a week to this class and actually teach how to do predictions/segmentations and more data science applications.

It was more of a 4.5/5 course! The instructor was very clear with the explanations. The quizzes were very good as they tested the concepts covered in the videos. The best parts were the programming quizzes and the final peer review assignment. The programming quizzes were a good way to have a hands on what had just learned and the peer review assignment was my favorite part. It tested everything plus we get a chance to explore fellow students work.

I liked this course, but for starters it's a bit fast. I knew almost all the information due to taking a previous data analyst course. I don't like how the work is just shown on slides. The week challenges don't really justify your answers, whether right or wrong, they don't explain how it's correct or not. And the end of the course challenge was a bit challenging, especially someone who is new to everything. So, that's why I give the course a 4.

The course content is generally good, but the final work, in my opinion, needs to be adjusted to work better. I completed this course in a relatively short time. However, the final work took me a lot of time to do some of them were quite confusing. I was quite frustrated by this work and I found a lot of people had the same feeling. I think improvements needs to be done to the work. This lectures, however, is worthy to participate in.

This course has all the basic information. But I didn't like the examples, they were poor. I could only see the result of SQL queries, but there were no screenshots about the table with which we are working and what was in the beginning. Moreover, not SQL queries in the lectures had even the resulting screenshot table. And, also, as for me, I prefer the [ESS QUE EL] pronunciation rather than [SIQUEL]. I recommend this course!

It's not a bad course for the basics. I already worked in IT and knew SQL, but I wanted to brush up and try the course. I knocked one star off because some of the final seemed odd. Importing the data seemed troublesome, and I had some issues to work around. Also, I had never used SQLite before, so it was a learning curve. I am used to MS SQL, but it was nice to play with another database and other tools I am not used to.

Good intro course, which doesn’t just cover the basics of SQL, but also usage from a Data Science perspective. Only observation is that the speaker is not so fluid, and obviously very nervous at the time of video recordings. Particularly Week 3, I couldn’t follow the Joins subject due to being so poorly articulated, so I ended up learning from the SQLite Tutorial site instead. Overall I did enjoy it and would recommend.

I really enjoyed this course, even though for a few moments I've got a feeling that the tasks were a little too difficult compared to what had been explained. But, I re-watched again and again the videos, reviewed the key concepts and peer comments, and in the end was able to make it. I highgly recommend this course to absolute beginners just like me, it gives you useful insights on what the Data Science is about.

The course is well structured, but the time needed to complete it (if the person is not used to programming languages) exceeds what the course says. In addition, the only drawback of the course is the final assignment. It is sometimes time consuming and the questions are in some cases poorly worded deriving in learners confusion ( a lot of discussions in the forums have been opened because of this matter).

I think the course covers most of the theory part. It needs to add more of the coding lesson and quizzes as well. For instance, the small questions we receive during the video, there should coding questions as well. When we receive the coding questions directly in the coding assignment at the end of the week. It is quite difficult to do these questions. Overall, it was an amazing learning experience.

The course is very informative and can be easily understood. It helps me to grasp the language easily and apply what I've understood through the exercises that they had. I think there's an incorrect answer on the peer review assignment about querying the 'Avon' and 'Beachwood' as the answers, and my answer as well, of the peers that I've reviewed is the same but the provided answer is different.

I enjoyed the course and feel like I have a good grasp on the common SQL applications, processes, functions, etc. The videos were informative, but I wish there were more examples (and more examples to actually work through and practice with). Overall, I think this is a really good course to learn the basics of SQL and the final assignment is very thorough and helps solidify that understanding.

Could have more visual examples, especially showing the output of queries. Also, could have a couple of additional videos in the end, showing some problem-solving situations, as I struggled a little bit with the questions on the inferential part of the final project. However, it was a good course, the length of the videos was perfect and it was very well divided. I think I learned a lot.

Course content was very strong.

Unfortunately, the environment for exercises and the exercises themselves, not quite so strong.

An antiquated installation of SQLite needs to be updated to support many "standard" SQL functions. The Yelp dataset for the final project is limited and the limitations on the analysis environment made it difficult to derive "supportable" inferences or insights.

Pretty good course for learning SQL basics as someone with no experience. Videos don't always flow super well which sometimes makes it harder to understand what the teacher is talking about.

Would have loved to see a diagram of the tables that data was being pulled from on the same slides as the syntax. Sometimes I felt confused about which parts of the code were tables vs columns, etc.

Overall I really enjoyed this course and the structure of it. Sadie is really good at explaining the concepts and I felt like I was constantly engaged in what was being taught. I felt some of the example databases were a bit out of date in terms of the data used for years (querying something in the past 15 years, but the database is all from early 2000s yielded all or nothing results).

I found this course to be a good introduction to SQL. However, I noticed that there are some minor mistakes in the downloadable PDF files - some don't align with the video lectures and some slides are wrong. A few questions in the final peer review assignment were also very ambiguous. With that being said, I would still recommend this course to anyone who wants a brief intro to SQL.

I learned great thinks about SQL I was looking for a long time. And I only find it step by step in this course. The course is very well structured. My only disappointment was about the final assignement. I would have liked more guidance or a correction by teachers, because I have certain notions that remains a little bit uncertain. But THanks a lot for the course. Brings me a lot.

It would have helped me to have more "hands on" use of the concepts right after they are presented instead of after many concepts are presented and then having to try to remember all of them. This is how you do this, then do it. It's like how Code Academy does it where they give you one step at a time to do and then on to the next step but not necessarily broken down that much.

A good, clearly-taught course. I feel like I've learned a lot and am CERTAINLY more confident with SQL than I was starting out. I'd be interested in an advanced course by the same people.

My only beef with the course was that some of the questions in the graded quizzes weren't clearly written, and this gave me a lot of grief (thus, 4 stars). Please consider vetting the questions.

The course is great! But the problem is that it would be better to work on real-work SQL application such as SQLite (which is prposed by the instructor) or other IDEs. It is just my humble opinion. But, the content of the course is super, and the coding assignments is lovely part where a learner understands what he/she has learnt and implements it! Huge thanks to the instructor!
