The practice parts for sql was limited with free trial of Sandbox.So I couldn't use some functions in query like UPDATE.The course was good though.

I really like this course learn and understood a lot of things .For SQL and Advance SQL I feel that should be taught more.

Enjoyed the rest course.

A LOT of information in this one, but feels great to put pieces together and start to feel like you are getting an overall understanding of things.

If you are starting your career in Data Analytics then this course is for you and if you have experience in this field then don't do this course.

This was a class that took us into a deeper dive of what the cleaning process is about and what to expect and plan for regarding data cleaning.

Useful information , simple explain & realty data cleaning Methods & tools , Really Thank You Both "Google & Coursera " for this opportunity .

I love sally she's different from other instructors she's actually enthusiastic and finally the course sets foot on something finally hands-on

I'd like to get some more practice using SQL queries and spreadsheets tools. Maybe you can offer optional resources to anyone that want it.

Just as awesome as the other courses I have completed, yet had some complexities happened as to activating the BigQuery paid trial version.

Very professional content, i enjoyed learning through it and understood a lot of new functions and techniques for data processing(Cleaning)

A good course, that covers the important aspects of data cleaning. It is very informative and easily understandable, even to beginners

Sally's enthusiasm is infectious. But I'd expected more SQL hands-on lab using Qwiklabs. Where did it go as seen in previous courses?

A great opportunity to learn the basics of sql and spreadsheets. I think that the process of cleaning data is the most usefull part.

Decent overview of data cleaning in SQL and spreadsheet. Honestly, a bit lacking in actual skills application or skills training.

not so clear with sql commands explanation, needs more details and clear examples, and more examples and more practical quizes

The course is very important and difficult to understand , I would suggest to provide MORe exercises for student to learn SQL

Thank you so much for including this topic in the course. Much appreciated.

I am enjoying so much and am keen to learn more.

It was an awesome experience and the instructor was so radiant and her way of explaining things was absolutely enlightening

Excellent course, although I feel a little deeper explanation of SQL is needed for those that aren't very familiar with it.

A good course, however more SQL functions can be added which can be handy with informing of the nested statements in SQL.

Excellent presentation, examples we can connect with.

This course and others done earlier have great tutors. Thanks to all.

I would like to see a chapter where how to treat nulls, errors and other fixes, when to delete dirty data, when to fix it

satisfied with the resume section but you could have add more about the actual process part. it was not much of challege

Covered lots of info, this instructor was great and sounded natural. Much easier to listen to than the others so far.

Sally instructor is too good to explain and energetic person. I prefer to learn more in future in coursera google.
