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.

By taking the course you can learn how to use the principal commands for database queries using SQL and the practice exams help your to develop the ability to perform the theoretical knowledge

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.

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

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.

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.

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.

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

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.

Actual course was interesting and engaging. The final assignment had questions that were not written with enough detail. I was also offended by language used by a reviewer.

Great course. Helps to learn the fundamentals but there are not enough opportunities to really practice the coding aspect, which is what I wanted to get out of the course.

Great course for SQL, still pretty beginner level, but would recommend some previous SQL experience here as the section on joins and sub-queries is a little challenging.

Very nice training videos. The assessment in the end was a bit far from the training but maybe it is also the question of knowing the data and practice of assessments.

Video's were very helpful and well organised. The end assignment however was badly phrased and overall confusing. Therefore it took way longer than the stated 2 hours.

This course is extremely helpful,4 start for that.Only if it had assignments along with the sample data to measure the range of our learning will be much helpful.

Lectures build at a slow, comfortable pace, but be prepared to discuss things on the message board, and read classmates' comments, or the quizzes will rock you.

I wish there were more practice exercises in between the videos. It would also be more helpful if there were more visuals/animations to accompany the lessons.

Great for begginers, I'd suggest to learn with W3 school sql tutorial in parallel as it has more concrete examples and functions you can try by yourself.

Overall this course is quite good to get a first understanding of SQL. Although i missed some more explanations or examples for complex data analysis.
