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.

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.

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.

The structure and guidance provided on the final assignment was very poor, resulting in far more time required to complete than expected.

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

1.Very basic course.
2. Assignments level does not match with training level.
3. Need to provide class which includes query writing.

The teacher was not readily available to answer questions. The course was alright but I do not feel prepared to use my skills yet.

Very slow and badly organised start of the course with no to very little practice of how to use SQLite before the coding quiz.

The first exercises are still ok. But the final exam is really a mess. The questions are not as precise as they should be.

Too much talking in videos with less examples. The exercises were vague and not enough information was given to solve them

The videos had the wrong emphasis, and were far too long.
More time should have been devoted to the exercises/quizzes.

Not satisfied. There are better MOOCs for SQL/Data Science out there. I wouldn't recommend it for a SQL beginner.

Great information, however, the site that host the datebase for the quizes is outdated and no longer supported.

The course is good in itself, but answers circulate on the internet, making the certificate not very meaningful.

there is a lot of questions about how the questions were asked, i highly recommend you do see the discussions

Not enough examples were shared.
Certain concepts were explained without telling their underlying basics.

There are so many issues with this course. The lectures, while generally clear, are obviously read from a teleprompter, with no slides or real exercises provided. They lack a lot of substance and examples to fully illustrate the content, and have no interactive components. The instructor is clearly extremely capable and knowledgeable, but is unable to convey any of that information due to the structure of the lectures.
The assignments meanwhile are way too difficult compared to the lecture material and severely lacking in feedback, explanation, or clarity. Half of the questions either have blatant errors, confusing wording, or requirements impossible for SQLite. Maybe this was partially my error, but it's not like the course was very helpful. In one of the lectures, on using DATE, the example in the lecture is formatted incorrectly, leading to a lot of trouble when doing the Quiz.
Some questions will ask you about "correlation" or "predicting", which is fine and all, except for the part where SQLite doesn't support many of the fuctions neccessary for such analysis.
I cannot recommend anyone take this course. There are maybe 4 hours of actual content in the entire course (including quizzes and assingments), except it'll take you significantly longer to complete as you sit there confused by the questions. Yes, you'll learn something, but you also could've done the same with a free tutorial somewhere else.
The forums are filled with people confused by the formatting, phrasing, or structure of assessments. Meanwhile, no effort is made by the instructors or UC Davis to correct the many issues here nor answer any of these posts. It's frankly an embarassment for a school like UC Davis to be putting out such low-quality content, even if it is from their extension program.
