Overall a great course although I'm not sure how well I would have picked this up had I not had prior experience. I used this course as a refresher after having dabbled in SQL a few months back and hardly touched it until recently. This course did help reinforce concepts and better taught ones I was less familiar with. I also liked the amount of problems that were provided and the various resources. All that said, the lecture method doesn't feel the strongest for teaching the content in the depth it requires - at least for me if I were a complete newcomer.

The course is informative, but there should be more hands-on type questions mid-video. Internalizing information would be much more efficient if there was more than just seeing results of queries and answering poorly worded questions. The final assignment can be one of great effort or minimal effort depending on the individuals interest in trying out complex queries that are out of their comfort zone, but both sides of the coin end up with the same certificate in hand. So, just like most courses in life, you get only what you put into it.

I thoroughly enjoyed this course as my first experience in Coursera. The lectures were presented in a well paced manner and the information was sufficiently broken down. However, the first few weeks suffered from insufficient assignments to reinforce the concepts learned. As a result, the final assignment was well beyond the normal intensity of the course and I felt unprepared. The final assignment appears to be developed by someone other than the core instructor and has a completely different understanding of the course scope.

Overall I think the course was pretty good. I think a lot of sections could have used more examples, especially of queries that combined several different types of clauses. There were also too many "choose the better answer" type questions in the weekly quizzes with more than one correct answer. Finally, the wording on many of the final assignment questions was terribly unclear. There are dozens of posts and questions about these on the forums. Ironing out these deficiencies would really help improve the overall course.

The course addresses all the topics necessary to start using SQL for profiling and analyzing data. To improve: 1). For various topics, there weren't enough examples and forth these themes could be confusing 2). It's too much visible that the teacher is reading a teleprompter and there were occasions where the sentences are not well connected, and at least for non-english speakers, this could be annoying and confusing. The assignments are well designed, and in these exercises is when you really start to learn.

This course has improved my SQL skills and let me further my knowledge of Database Management System. Also, there are some coding assignments helping cultivate my hands-on SQL coding skills, especially for data science.

However, some of the lecture videos felt disconnected from the coursework, honestly. The lecturer just read out verbatim, showing too few examples and too few coding tests. Moreover, the assignments were too few so I supposed I should have to take another course so as to get massive progress.

It's better if someone can give learners some advice on their project. It's really hard to finish a complete project by the learners themselves. What's more, as a starters, everyone knows a little, only some basic knowledges, so we don't know how we did on our project. It's better that someone who is more professional on this course, like TA or someone who can give us some advice on our project and it could be better if we can have some sample answers after we finally finished the complete course.

Hi, I just started this course, and so far it's great, but in Data Models, Part 1:Thinking About Your Data, I think there is a typo in the last question for this module. One of the answer choices is "A translation system for used to communicate with Data Scientists" You probably meant to write "A translation system used to communication with Data Scientists" (leaving out "for") Just figured you might want to know so you can change it before more people sign up for the course. All the best!

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.

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.

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.

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.

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.

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.

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.

Thank you
