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.

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!

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.

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!

The course covers wide range codes and I think it really helps you to understand how SQL works. I think after this course, you can do the basic SQL in real life. However, the assignment itself could be a little ambiguous. It requires quite an effort to understand. You could always use the discussion forum to find the answer, really, everything is there. Overall, great course.

Good overall course, I like the order of topics introduced and they're application to real world events. My only request for this course is that the topics go a little more in depth (explanation of more complex examples) and that there could be an optional video to watch where the instructor does the coding quizzes, and explains their reasoning behind the queries they create.

It's a good start for learning SQL. However, intensity of the lessons does not match the quiz and final assignments. Lectures are more simple and easy to understand but not enough to complete the coding assignments. You need extra resources or help to finish the course. After every quiz or coding assignment, i would expect to see the correct SQL queries to see our mistakes.
This course covers many great issues.
My only problem with this course is the way tackle SQL on the first 4 videos. I think I totally gut confused.
After, I read some articles which provided on reading material I fully understand the concept.
My suggestion is to change the sequence of some videos and put these videos after the student is done with reading part.

The course is pretty good. In particular, the quizzes and assignments are very useful to understand the concepts that are being taught in the course. I enjoyed it!
However, I will give only 4 stars because regarding the lecture videos I would have preferred that the instructor coded along with a sample database instead of showing the code snippets in a power point.

I thought this course was really useful for beginners in SQL, my only issue is that some of the concepts were not explained very well. I never really understood how to qualify tables, there were things you could do with text that were mentioned but never explained, etc. Maybe I missed something but some of the concepts they were very vague but then on the quizzes

The modules are carefully planned and precise. The reading materials are really helpful to get a better understanding of the subjects, and the quizzes at the end of each week are thorough and cover every important point. The one thing I can think of that can be improved is the way the teacher is presenting the lessons, it is unfortunately a little bit monotonous.

Thanks to this course I've found a job as data analyst, and now I write sql queries every day, which eventually make me sick of the select......from.....inner join*n......group by......lol Anyway it's a very efficient course that gives you all the necessary building blocks in a week (I finished it within several days). And the rest is gained gradually from work.

This is a great opportunity for a beginner to learn the basics of SQL for data analysis. I'm confident that I can put SQL on my resume now! The end of the course is pretty worrisome though. It takes a few days after you've submitted your final for other people to finall review yours. You'll end up doing wayyy more reviews just to get others to review yours.
It is a good course for beginners who are not familiar with SQL. You don't need to install anything but can still practice through the quiz to enhance the basic commands.
The problem is there are some mistakes in the course material and these wrong explanations may be misleading for the students who are new and don't have sufficient knowledge of SQL.

I thought the course was, by and large, effective at communicating the lessons. The weekly quizzes and practice elements were also great. My only sticking point was in the final assignment. Having to update a .txt file (which is notoriously difficult to format) and review others' .txt files makes for a bumpy experience for the final assignment
