Reviews summary

Hands-on bigquery for semi-structured data

According to learners, this course offers a highly practical and hands-on approach to working with semi-structured data in BigQuery. Students particularly value the well-structured labs and clear, precise instructions, which make complex topics like JSON, arrays, and structs accessible. Many found the content directly applicable to real-world BigQuery scenarios and instrumental in filling specific knowledge gaps for their data analytics or engineering roles. However, some learners noted a lack of in-depth theoretical explanations, feeling it was more of a 'cookbook' for operations rather than covering the 'why'. While beneficial for those with some SQL or BigQuery experience, it might serve as merely a starting point for advanced users seeking optimization techniques or pose a challenge for absolute beginners without foundational context.

Generally stable, with minor, platform-related slowness sometimes noted.

"The instructions were clear and precise, and the environment worked flawlessly."

"My only minor gripe is that sometimes the lab environment can be slow, but that's a platform issue, not the course's fault."

Features well-written instructions, making the labs easy to follow.

"The instructions were clear and precise, and the environment worked flawlessly."

"The instructions are clear."

"It's concise and gets straight to the point without unnecessary fluff."

Equips learners with skills directly applicable to data roles.

"Extremely useful for my data analytics role. I had some prior experience with SQL but not specifically with BigQuery's semi-structured data types, and this course filled that gap perfectly."

"The course content is up-to-date and directly applicable to real-world BigQuery scenarios. Great job by Google Cloud."

"The exercises are clear and relevant."

Provides effective, hands-on learning for BigQuery data types.

"This lab was incredibly useful for understanding how to work with semi-structured data in BigQuery. The hands-on approach truly solidified my knowledge..."

"Excellent course! The practical exercises on handling JSON data and arrays were exactly what I needed for my current project."

"The labs are well-structured and very effective. I particularly found the sections on `UNNEST` and `JSON_EXTRACT` to be extremely valuable."

"I learned a lot about JSON parsing and unnesting complex data structures from the practical skill development."

Focuses on practical application, less on underlying theory.

"The content is okay, but I wish there were more theoretical explanations before diving into the labs. It felt a bit like a cookbook without explaining the 'why' behind certain operations."

"I expected more in-depth coverage. While the labs were hands-on, I felt they were too basic for someone with intermediate BigQuery knowledge. Good for absolute beginners, maybe, but then it needs more foundational theory."

"This course provides a solid foundation, but it's not an in-depth dive into advanced optimizations."

Best for those with some BigQuery/SQL, less for pure beginners or advanced users.

"It assumes a basic familiarity with SQL and BigQuery, which is fair, but some parts could be slightly more detailed for absolute beginners."

"If you already know some concepts, it's fine, but as a complete beginner, I struggled a bit."

"Good for absolute beginners, maybe, but then it needs more foundational theory."

"For those looking for more advanced techniques, this might just be a starting point. Still, for understanding how to manipulate arrays and structs, it's very effective."

"I expected more in-depth coverage. While the labs were hands-on, I felt they were too basic for someone with intermediate BigQuery knowledge."
