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 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.

Honestly it's not obvious why it is called sql for DATA SCIENCE.
In my opinion it's just SQL Basics.
It's pity that there weren't window functions.
But generally the course is good enough.

great beginner class and also teaches critical logic thinking, which is what most business want out of Analysis type of jobs or Data Science in general, something useful and actionable.

There were a handful of errors in the video lecture's text on screen and lecturing. Some parts were hard to follow because of that. Otherwise the assignments and material was helpful!

Great course work! Loved the pace of the course and the examples. The instructors speech was pleasing and easy to understand. Would have loved more difficult SQL queries for practice.

Thank you to everyone who is in charge of this course. But the training platform is not good and does not support all orders sql and there must be training after each lesson. Thanks

A great course to get started with SQL.The course is well structured and the pace is just fine!Coding questions at the end of the module really help in testing the concepts learnt.

Very good explanations during the course, but we were working with data that weren't making sense, like texts data types.
A lot of records without real foreign key in their tables.

its a good course to learn basic SQL but it teaches SQLite which pretty much the same as SQL with few changes. The course is good with many assignments but the test was tough.
