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 thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

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 videos and explanations are nice but it would be excellent if the running of SQL code and its outcome
Will also be shown in the video so as to explain the minute difference between two functions in the code

The course was very well organized and the instructor was fabulous. I just wish we had received more practice exercises as I feel that I know the material theoretically well but practically I'm less confident.

The course is mostly based on theoretical content, which makes it a pretty good foundation for those who have never touched SQL. I would rate this course 5 star if it provided more examples and applications.

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 final project was way harder than the materials taught in classes, It would be better if they teach more before letting us handle such challenging task. Still the course was great, and I learned a lot.

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.

I liked most of the course, but in week 4 it felt rushed. The code shown in the slides wasn't formatted consistently all the time.
But all in all thanks for the education. I would recommend the course.

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!

Sadie is an excellent teacher. The course was enough to get me started. I still feel that I need to continue working with the concepts to become more proficient and more confident in coding.

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.

Best for new learners who started their journey in the SQL world. But the video lectures are simpler than the assignments and quiz, the lecture should also include more question solving
