Great course to learn DB concepts. Lectures are well organized and assignments built up difficulty smoothly. At the end of course, student feels familiar with DB/ tables creation and queries.

The 2 main assignments are very challenging, you will learn a lot. You cannot complete this course without learning basic postgres. Big like, great application

No assistance and poor explained assignments resulting in tons of time lost looking for tutorials and videos somewhere else, can only make me never recommend it to anyone. Everything I've learned and applied was from somewhere else anyway...

The course is a very shallow overview of core db concepts. Discussion forums are silent and there is no feedback from course tutors.

This course is very difficult to follow. It is clear that the instructor knows the material, but he has a hard time explaining the concepts and details in the videos. When he gets stuck trying to describe something (which is often) he quickly just moves on leaving learners still uninformed. The assignments also seem to assume a solid understanding of SQL and databases which is frustrating because this course is supposed to be core database concepts. For example, they want you to create an SQL script, but that process is never explained well. If you don't already have a good bit of experience with SQL, databases, coding, and other topics of this nature, I do not recommend this course.

The assignments are just poor. You can create SQL queries with different SQL JOIN structures which can lead to different order results with the order that is expected to be hardcoded. The grade output says that you fail test case without any kind of explanation which make the whole situation to be a complete disaster.

automated grader is impossible to work with.

I feel really bad giving only one star but that is because the course was not well executed. The slides were hard to interpret and the concepts were generally not well presented.
