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.
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.
The course gives basic elements of SQL, but there is no practice in the course (beside graded assignments), code is shown only in presentation (you cannot copy and and see how it works), and learning SQL without constant practice is nearly impossible. The peer graded assignment is messy.
Course is very theoretical, the teachers just reads presentation with SQL functions, there's no way to actually learn SQL by listening to it. Also she doesn't provide information about essentials of databases, so the beginners may not understand the concept of it.

It is a good conceptual introduction to SQL, but as many other reviews say: it lacks the real hands-on work that teaches you coding skills and good practice in choosing different query strategies.
Overal I am on the fence on whether it was worth the costs..

The mistakes in the presentations and the massive ambiguity in the final assignment were a complete letdown for me. All in all, I did learn everything that was taught, but I wonder how much of that was made possible thanks to my previous experience in IT.

Good course to learn the basics but not worth the price you pay. Until week 3, everything is fine, but week 4 is a disaster. The final assignment is very confusing and sometimes it is hard to know what you are being asked. Not recommended.

The videos were not as informative as I would've liked them to be. When you input incorrect code there weren't many resources to find where your mistake was. It would be helpful to have a tutor or someone to chat with for help.

The course has no transcript for review. And the system of SQL exercise is also wrong when you are using “WHERE” Clause and “=” signal. Because of the mistakes of system I even can not make any progress. Please check.

The course went fine up until the final assignment. It was very irritating to do, because of the incomplete database, broken correlations, different tables stating different things, which should've been the same, etc.

bad experience on exercise:
In the course, you will learn different functions of sqlite but they merely bring you along with examples but pop out with tons of different exercises without giving you a single hint
By Yian G•
The instructor spent too much time on unnecessary and self-explaining topics, and on the other hand failed to explain some important details. I ended up skipping much of the course and googled a lot by myself.

Decent introduction. I recommend https://mode.com/sql-tutorial for a better introduction to SQL.
Assignments are very badly designed. Also the questions in the final assignment are unnecessarily repetitive!
By Sajiri V•
The lectures were not easy to comprehend for a computer language. Though the course mentions it is a beginner-level course, the lecturer jumps to a certain part where there is a learning curve expected.
By Ligeng X•
A little too easy, not challenging at all, given this is a beginner level class, I'll give it two stars. You could finish the whole course on Saturday if you get up early plus Sunday if you do not.
By Fan Y•
Even reading the prompter throughout the course, the instructor has been extremely nervous and unsmooth in reading. This is the biggest downside of the course and eclipses its good sides.

Hi, First of all I don't like peer assignment concepts. second especially in joins videos if you have shown examples with output, little elaborate, will be more useful.
I wish that the instructor used examples that mirrored the type of questions in the coding exams. We did not cover all the material in the coding exam.
By Darren R•
The structure and guidance provided on the final assignment was very poor, resulting in far more time required to complete than expected.
By Riccardo B•
too much theory, I needed something more 'pratical' that allowed me to start using and write code and not see a lot of slide with code
By SARTHAK S•
1.Very basic course.
2. Assignments level does not match with training level.
3. Need to provide class which includes query writing.
By Carolina E•
The teacher was not readily available to answer questions. The course was alright but I do not feel prepared to use my skills yet.
By Mathias M•
Very slow and badly organised start of the course with no to very little practice of how to use SQLite before the coding quiz.
By Seidler C•
The first exercises are still ok. But the final exam is really a mess. The questions are not as precise as they should be.
By Yash K•
Too much talking in videos with less examples. The exercises were vague and not enough information was given to solve them
By Bill P•
The videos had the wrong emphasis, and were far too long.
More time should have been devoted to the exercises/quizzes.
By Christos A•
Not satisfied. There are better MOOCs for SQL/Data Science out there. I wouldn't recommend it for a SQL beginner.
