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.

Quite easy. The peer-reviewed assignment is also very easy.

Important topics like window functions are missing.

Too much theory and very little or no practice
By Deleted A•
The course is basically theoretical.
Good general basic introductions.

Really bad. I'm trying to be fair here, and I understand that there are reasons the instructors made some choices that they did, however:
-You can't teach a course designed for absolute beginners and not help us install a chosen software and explain the interface. I felt SO LOST trying to download SQLite on my own, and then find out the instructor chose to teach a software with NO USER INTERFACE from the download. Why would anyone chose SQLite as the software FOR A COMPLETE BEGINNER: I have no idea. I ended up using a different course (see below) and used MySQL as my software (free, great user interface, not so intimidating for a beginner.
-I can't stress this enough: THIS IS A THEORETICAL COURSE. There is no videos in which the instructor has an SQL software open and you code along with them. IF THAT'S WHAT YOU WANT go to "Programming with Mosh." The way that this course works is, she just talks about SQL: you never are given a database from which to query / retrieve / test your programming. Like, how is this even a course if you're not at least providing some sample data to work with?
I'm really disappointed in Coursera: I've completed two specializations here already, really enjoyed each and had no desire to leave the website, but after this I'm going to be much more careful and looking at other websites like Udemy.

Weeks 1 - 3 contained good information and had good problem sets. Week 4 totally drops the ball. The lectures do not fully flesh out the many uses of datetimes, cases or views. The problem sets for week 4 should be much more extensive to practice these concepts. The lectures on sql for Data Science are fluff - no skills are included; and then the student is expected to perform these skills in the peer reviewed assignment. The peer review assignment has several poorly specified questions. Overall the lectures could be improved by showing the ER diagrams for the tables the lecturer is referring to rather than only showing a query. Many lectures should be reshot where the lecturer misspeaks/does not complete her thought, or where she burps while speaking.
