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.

A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

I think the peer-reviewed assignment should be only on the last portion of the last project for the custom data analysis part only. Because the other questions are very technical and can accelerate the process of grading :)

I enjoyed the course and learnt quite a lot in a relatively short time. My only critic is that I felt there was a gap between the depth with which each topic was cover in the lectures and the complexity of the final exam.

It was a great experience to have a course. It was my first ever course as Online. I am thinking that the journey has started and it will never end. I also have selected the next course that I will complete in the next.

I believe this course focused entirely on retrieving data and no emphasis was given on creating or modifying tables. If these topics would have been included then it can come out as a complete package for learning SQL

This is a great course for beginners. One of the things which can be improved is to have more practice questions to use all the concepts introduced in the lectures. For example: I did not get a lot of chance to create

I have prior knowledge on SQL as a programmer. However after studying this course I got a another flavor of SQL from the Data Science point of view. I loved this course and the trainer as well. Thank you coursera.

Some examples in the later part of the course is a bit difficult to understand for those with limited programming background. Few broken down, step by step examples of complex queries will be highly appreciated.

The first two modules are okay and easy to understand, but the last two modules are little bit confusing, and from my perspective, the instructor is simply reading the script rather than teaching a lesson.

The course content itself was awesome! Be ready for some technical glitches though. As long as you pay close attention to the forum, you should be fine. Overall, I would definitely recommend this course.

I think the peer review exercise is a great way to test your learned skills. The lectures are easy to understand but I think it would be better if you added more info about the structure of ER diagrams.

As an introductory course is well designed and well explained. The supplement lectures were of great help. Maybe a little introduction to Analytical Functions should help to make it completely awesome!

Overall the content is good and the tutor is also good in the explanation the codes and concepts.
One suggestion there should be a more practical example and as well as how to run a query on a dataset.

Although several concepts are not explained very clearly and a number of assessment questions are unclearly worded, this course is otherwise an excellent introduction to understanding and applying SQL.

The course is nice but I suppose the PowerPoint presentation that accompanies it could use some effects to show us the clauses one by one, as they are spoke. That would make understanding them easier.

Good course for beginners.
- classes are fine
- quizzes evaluate quite well your understanding I think
- the final assessment contains plenty of VERY ambiguous questions and I think it should be reworked

Please Included examples while the instructor is teaching in the video lectures. The instructor is very talented in teaching but due to lack of examples in the video it downgrades the overall course.

Did not need to be a peer review assessment, most of the tests lacked creativity and could be automated. The peer review component should just apply to the creative components that can be expanded.

The contents and explanations on the course are good, even for people with no previews coding experience (like me)... Would be great to have a better structured way of work for the final excercise

Great course for beginners, very clear and instructor share useful tips. The only reason I don't give it 5 stars is because I think there could be more material related to date and time functions.

Videos are a bit lengthy course could be shorter by 10-20% from a time perspective with the content staying the same. Overall good course for anyone that need to learn or to refresh their skills.

Presentation was Nice, But Skipped few basic concepts in the beginning like types of DBMS and how why we use RDBMS in particular.
Also could have explained better on few topics in Week 4 sessions

It's so pitying that we can send more than one time our end test. That decreases the quality and credibility of the end certification.
But the course is very well done: nice teacher and content!

Nice that it doesn't expect us to know SQL and programming well. But not nearly enough exercises to understand how to do the queries well. I am feeling lost on the practice tests especially.

A well-structured course for those who are eager to gain knowledge about SQL.
The activity, test, and the mentor are very good and the best part is they showcase a bit of industry knowledge.

Great course, with well explained notion, well documented. The only thing I could add is that some exercises could be updated. Creates confusion when trying to solve.
