Really helpful with enough theory background and practical exercises

Absolutely important topics such as handling nested fields, query optimization techniques and advanced functions are covered. Excellent content!

good for Data Analyst

I learned lots about the structs and arrays and how it could be used to improve performance by creating parent child relationships instead of doing expensive joins

Very interesting and nice to follow

Muy buen curso

Super GREAT job Evan! This is the most valuable BigQuery courses I've ever learned!

Excellent course; I only wish there were a much longer and more robust lab on optimizing query performance, after all the tips we learned in the corresponding lessons.

Some useful insights here that I can immediately apply to my work in BigQuery.

Good but lack of sql example and sql questions

nice course

good

Excellent course on BigQuery, Dataprep, DataStudio and Dataset Secure Access topics. Hoped to have more on Datalab and Bigquery, and also more difficult labs, but it's ok.

Overall this was a great course with great material.

Thanks!

Awesome. This part of specialization is worth time and money spent.

Course provides a high level understanding of what can be achieved through GCP.

Lots of in-depth material covered in this course, including nesting of data structures. Also provides high-level introductions to Google Data Studio and Cloud DataLab.

Very helpful to know advanced SQL querying even if I don't really have to do it myself.

Very informative and valuable learning. Enjoyed both the Google specific content as well as the general data analyst content.

Fantastic course with great focus on advanced subjects.

Thanks for the course, the lab practices are very useful, would be great if there are any project assignments

Excellent course, material and labs. Congrats for Google professionals and Coursera staff. Keep rockking, cheers!

Great insights!

Useful practical course, especially about performance optimization. Window functions have many options, it would be nice to add window size description with practical examples or links to them.

A lab on notebook would have been nice.
