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.
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.

should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.

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

Assignments could be more basic.
The level of difficulty should gradually increased.
Superb instructor though.

More explanation of concepts is required. Also it would have been better if SQL code was explained in depth.

Instructor should have explain each code by performing practically on pc instead of showing only image.

i think it will be better to learn using mySQL. and more info about dataset will be helpful to note

not really relevant to 'data science' its more of a general basic introduction to CRUD and joins
автор: Ayush K J•
examples for important concepts were lacking like the use of GROUP BY and CASE statements

Course teaching was excellent, but the final assignment questions were terrible.

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

Quizzes poorly and ambiguously worded, database carelessly extracted

It could be harder with some excersice that make the student search

Good content but the questions are badly worded and need updating.
