Overall a lot of knowledge and an interesting course. I was disappointed that the last part focused more on Machine Learning instead of on databases, data lakes etc. as I feel this would be more relevant to the specialization.

I did not like the assignment as they were not demanding enough. Majority of the code was written for us, it did not require us to analyze the code more to actually understand what we are doing and learn it.

Very great introduction to the Spark SQL and databricks environment worked perfectly as a hands-on.

It would be great if the course covers the Spark ML applications. We used sklearn in the course and utilized a trained model by using the user-defined function. I wonder how it compares with the case where we use Sp ark ML for the training as well.

The course was a struggle. I didn't take calculus or trigonometry. So, the square root means was a bit over my head. It was nice that the machine learning queries were already in the assignments. However, it would have been helpful to explain them better. Then I would be able to understand why they are written a specific way and how to read them.

Positives - Just having SQL knowledge got me to learn how the large data can be processed using SPARKSQL. I had a great time getting hands-on experience for spark SQL notebook.

Negative- I just wish the videos are too paced as there was a lot of information to cover in all the videos.

It was very helpful to me.

I would improve the assignments' design. Sometimes it felt like something was missing and not very clear, at least not as it is in the real world. And I loved Brooke's way of teaching.

Everything was taught in a way it was easy to understand for a Layman. Practise workbook in Databricks gave lot of hands on experience. Got to learn about new concepts in easy to understand way.

This course provides hands-on experience in using Databricks's Spark. I learned a lot. I recommend people with some SQL experience to take this course for efficient programming skills!

It was a quick and challenging overview, but I thought it was well presented as a basic introduction to Apache Spark

Good course. Maybe little more details on how Spark works, Spark architecture would make the story complete

A good way to get started with Spark SQL. You might need some knowledge of SQL to get started with.

There should have been more assignments for practicing. Overall the course was structured good!

Pretty good. The exercises were good. I would have liked more of them.

Will be better if more practise and examples of Spark SQL is given

V​ery informative course that increased my knowledge of SQL

It is a good course. I have learned a lot about Spark.

Good introduction but assignments are too guided.

Liked the practical part and the instructors.

N​ote book for the last week is missing!

good for spark-ml, bigdata beginer

I found it very interesting.

Happy to attend this course.

Muy buen curso

Great!!

This course was a good introduction to Spark SQL, but they tried to cram too much into one course and ended up not being very clear about most of the material. This could be broken down into a specialization and it would be more effective. I got through by Googling a lot, and I already have a background in Machine Learning, but for someone new to the material it would be overwhelming. I wish they'd explained things like how parallelization works more effectively instead of rushing through too much material. The instructors clearly know their stuff, but they need to work on breaking these concepts down for people who don't have much experience in computer science.

I was disappointed because I still don't know how to insall Spark in my PC. I tried to install but it doesn't work. So I think it would be better if we could learn how to use Spark without Databricks. And the content is too superficial.
