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.

I think that the content in this course is poorly structured. It becomes way too challenging at the end. Also there are some mistakes in the videos which are not yet addressed even after repeated pointing out by learners in the discussion forum. It is surprising that UC Davis offers content which is slightly unprofessional.

The lack of ability to follow along due to no common software or commands was extremely irritating. The brilliant idea that I should investigate one online and figure out how it works was what I thought I was taking the class for. Why not choose an open source program and focus on the methodologies?

Lectures were very bad. It sounded like she was reading a speech that was written the night before, with grammatical errors and all. Both over-explained simple things, and under explained complex things. I did most of my learning on https://www.sqlitetutorial.net in order to pass the assignments.

the course is completely theoretical and not use MySQL with using the theory you can get help in work but real life database and application is not included in this course so if you want to learn and apply directly you can do that in this course, which decrease the interest in course materials.

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.

i liked the lessons but the last project is completly buggy and not easy to understand what they want from me. it's a pain and I really regret taking that course because after putting that much effort in it, it's very frustrating to has such a poor final test.

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.

No reference answers for practice questions and final project. Have no where to learn what to do is right or ideal. Poor function support. Some basic functions like Instr() can not be used. I'm done with this course.

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.

the video does not provide much infomation on how codes are structured. the readings are in pieces. and no tuitor for quized and homeworks. I would not imagine a 0 knowledge person would comprehend this course well

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

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!

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.

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.

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.

Didn't feel it actually helped me learn because there wasn't any step-by-step instruction. It just was videos w/script and then quizzes and you were expected to know the content.

The instructor is so hard to follow that it made me not want to continue with the entire specialization. Although I really like the challenges and the idea of peer-reviewing.

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.

Below expectation for such a high profile university. Luckily my basic background in SQL was enough to get me through the activities because the lectures were poor.
