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.
Well it was a short course, the assignments are a little bit repetitive (mostly in the last). The course reviews every 'practical' aspects of SQL, how to assemble the bricks while writing queries,...

Course would be much better if you can work alongside the instructor. Using presentation slides in a coding class is not ideal imo.

The lecturer maybe is a good data scientist but does not have the skills of presenting or explaining material in an easy manner.
創建者 Chan J J•
should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.
創建者 Chen K•
Course schedule was good , but content is a little short. To make improvement, should present some example during the video

This is a good course for basic knowledge of SQL but the quizzes and assignments are very confusing and badly elaborated.

This is a good course on SQL for Data Science. As you will particularly start from scratch and go uptil tedious methods

The overall format was quite good but it would be more helpful if more examples are included in the lecture videos.

This course is helpful for beginners, but I felt that some explanation weren't clear and quizzes were challenging
創建者 Saswata B•
More explanation of concepts is required. Also it would have been better if SQL code was explained in depth.
創建者 Smit P•
Instructor should have explain each code by performing practically on pc instead of showing only image.
創建者 Nick J•
not really relevant to 'data science' its more of a general basic introduction to CRUD and joins
創建者 Ayush K J•
examples for important concepts were lacking like the use of GROUP BY and CASE statements
創建者 Christopher M•
Course teaching was excellent, but the final assignment questions were terrible.

Clear instruction, but quite easy. Would prefer if it was more challenging.

The Assignment was mis worded and didn't reflect the content of the course

Nice course to get an introduction to SQL. Not so much practice material.
創建者 Abdullah F•
Just teaches SQL. Nothing is taught about how its used for data science
創建者 Simone D•
The course material seemed prepared in a rush, with several mistakes.
創建者 Greg L•
Quizzes poorly and ambiguously worded, database carelessly extracted
創建者 David A•
It could be harder with some excersice that make the student search
創建者 Daniel E•
Good content but the questions are badly worded and need updating.
創建者 Melissa V•
Need to take a more in-depth class to fully understand this class.
創建者 Matt E•
You can learn this stuff on your own. You don't need a course.

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