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.
A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

Presentation was Nice, But Skipped few basic concepts in the beginning like types of DBMS and how why we use RDBMS in particular.
Also could have explained better on few topics in Week 4 sessions

It's so pitying that we can send more than one time our end test. That decreases the quality and credibility of the end certification.
But the course is very well done: nice teacher and content!

Nice that it doesn't expect us to know SQL and programming well. But not nearly enough exercises to understand how to do the queries well. I am feeling lost on the practice tests especially.
By Aditya S•
A well-structured course for those who are eager to gain knowledge about SQL.
The activity, test, and the mentor are very good and the best part is they showcase a bit of industry knowledge.
By Gianina G•
Great course, with well explained notion, well documented. The only thing I could add is that some exercises could be updated. Creates confusion when trying to solve.

Honestly it's not obvious why it is called sql for DATA SCIENCE.
In my opinion it's just SQL Basics.
It's pity that there weren't window functions.
But generally the course is good enough.
By Raymond M•
great beginner class and also teaches critical logic thinking, which is what most business want out of Analysis type of jobs or Data Science in general, something useful and actionable.

There were a handful of errors in the video lecture's text on screen and lecturing. Some parts were hard to follow because of that. Otherwise the assignments and material was helpful!

Great course work! Loved the pace of the course and the examples. The instructors speech was pleasing and easy to understand. Would have loved more difficult SQL queries for practice.

Thank you to everyone who is in charge of this course. But the training platform is not good and does not support all orders sql and there must be training after each lesson. Thanks

A great course to get started with SQL.The course is well structured and the pace is just fine!Coding questions at the end of the module really help in testing the concepts learnt.

Very good explanations during the course, but we were working with data that weren't making sense, like texts data types.
A lot of records without real foreign key in their tables.
I am a beginner for this course.This course build my knowledge in sql. Joins topic was little bit tough.other than that ,I understand everything.I enjoyed this course very much.
By Sib S P•
its a good course to learn basic SQL but it teaches SQLite which pretty much the same as SQL with few changes. The course is good with many assignments but the test was tough.
By PRATYASHA M•
THE COURSE IS SO MUCH COMPACT AND EASY TO UNDERSTAND FOR THE BEGINNERS. THE VIDEOS ARE VERY MUCH COMPACT AND SHORT SO ONE CAN EASY UNDERSTAND WITHOUT LOOSING HIS\HER PATIENCE.
By Kirstin L•
Actual course was interesting and engaging. The final assignment had questions that were not written with enough detail. I was also offended by language used by a reviewer.
By Jack B•
Great course. Helps to learn the fundamentals but there are not enough opportunities to really practice the coding aspect, which is what I wanted to get out of the course.
By Спиридонов Д Д•
The course explains essentials of SQL well but practice assignments should be placed after every video containing some new SQL syntax to consolidate acquiring knowledge.
By Daniel C•
Great course for SQL, still pretty beginner level, but would recommend some previous SQL experience here as the section on joins and sub-queries is a little challenging.
By Aniko F•
Very nice training videos. The assessment in the end was a bit far from the training but maybe it is also the question of knowing the data and practice of assessments.
Video's were very helpful and well organised. The end assignment however was badly phrased and overall confusing. Therefore it took way longer than the stated 2 hours.
By Soham D G•
The course is interactive and apt for beginners. The pace is perfect. The flow of the course and the way to guide us to the right answers in the quiz could be better.
By Siddharth M•
Sadie did a great job with explain SQL concepts. Only thing I didnt like was peer review assignment for which I had to beg people to review mine to get mine graded.
By Bhavesh W•
This course is extremely helpful,4 start for that.Only if it had assignments along with the sample data to measure the range of our learning will be much helpful.

Lectures build at a slow, comfortable pace, but be prepared to discuss things on the message board, and read classmates' comments, or the quizzes will rock you.
