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 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.

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

Content is fine but I feel that the last peer review assignment could be improved by adding much elaborate data definitions and metadata to give better clarity about concept of fields. Just UML diagram doesn't suffice for in depth analysis. Also, please allow a better sql editor to use, just one query at a time is bothersome.
P.S: Good job!

I'm totally new to SQL and even as a beginner I found these lessons to be way too slow, assignments were interesting but the questions of the peer review were very difficult to understand. The teacher is very clear, the structure is logical and she's able to give good simple tips. I'll recommend this course for whoever wants to get into SQL

I had issues with week 3. I think the outputs should have been included with the code during the videos so the examples would be more helpful. The forums were very disorganized. I commented on a post and asked a question but didn't receive help on either. Overall, I was happy with the class and am looking forward to the next one.

This course gives a really good introduction to SQL, no pre-knowledge needed and it feels like the level reached at completion of the course is very satisfying for a 4-weeks program.
The final assignment is a bit confusing and could be improved, but the lecture videos and practice quiz at the end of each module are very well done.

Liked the lessons a lot, the examns and the assignment is slightly more complicated to the queries shown on the videos though. The level of exercises shown in the video lessons should be higher so students know what to expect from the exams and assignment. Aside from that, explanations are clear and the course is very enjoyable.

Great material and videos. However, the questions on the final are ambiguous and can be very challenging, and the final as a whole can take much longer than the anticipated 2 hours. On the other hand, if you can make it through the final, you will come out with a great introductory understanding of SQL by the end of the course.

I enjoyed the course and definitely know and understand SQL statements now. In the future, it would be helpful to provide additional tips on where to practice your SQL statements to help those of us who need that extra help.
The instructor was very clear in the videos which made it easy to follow. Thanks for a great course!

The course was informative and well- structured. However, I wish the course had more example problems in the lecture videos. I also wish the lecture sides showed the results of each query instead of just listing out the query. Overall, I feel like I had a good overview of SQL and some rudimentary knowledge on utilizing SQL.

The course is easy to follow, well-explained and have enough hands-on to reinforce what we have learnt! However, the assignment and quizzes can be improved. Sometimes the contents of the quizzes are not covered by previous videos. Over all it is a good class for both beginners and people who want to refresh SQL concepts!

Not so difficult with previous limited knowledge of SQL. Videos could be better with actually showing the output of the code that were included. First time hearing someone say SQL as 'sequel'... or is this how it's actually pronounced? Instructor had a calm and soothing voice, although her body language was messed up.

I like the course, it was well done and exposed me to many of the key features needed to continue my SQL learning. The websites and other resources were extremely useful. The only wish there were more opportunities to practice SQL coding, maybe guidance to another site with questions, or more sample quizzes.

If the final assignment was not so ambiguous (many questions are misworded leading to wrong SQL codes, it is almost impossible to decipher what is being asked exactly) this course would have got 5 stars from me. Otherwise I liked the pace of the material other than maybe Week 1 and I enjoyed the coding quizzes.

The course was great up until the final assignment which was very ambiguous. It was also a shame that they used such an old version of SQLite, where many functions are not available. However, I feel that it did fulfill the goal, which is to make their students be perfectly prepared for SQL in Data Science.

It was a very good course. A person with no prior knowledge of SQL can easily learn this course. I would like to suggest that for certain sections like joins, date-time, the course provider may consider introducing some animation into the lecture videos to illustrate how data is being linked/extracted.

The course is good but lacks proper explanation of queris and required some more illustrative way to show the handling of queries in videos.Requires proper graphics and additional programming interface to sshow and run the various queries discussed by the tutor in the videos for better understanding.
