Good Explanations of Concepts and Nice Tests. I got a trilling experience in completing the peer Assignments with keen observation and Analyzing of Concepts learned.Thanq for your course very much.

Nice course to describe the traditional data modeling (RDBMS) as well as various semi-structured and un-structured data modeling and management of the systems (Batch and Streaming data processing)

Would have more extra papers/material to read. The hands-on would also bring some problems/challenges without resolution to let us try by ourself (with answers).

I wanted to see more big data issues in the final test.

Course was very good, some concepts were a little tough to understand, like the graph network and other topics of first 3 weeks. But on the whole a very good course to understand basics of data modeling and management.

Decent course, fair information. Although sometimes instructors seem to forget the audience they are talking to, so it is hard to power through some lectures.

The final assignment is unclear in some passages, but it is a very good introduction to the modelling and management systems overall.

Really nice course. Had a chance to rediscover my data modelling skills. Surely looking forward to more courses in this specialization.

Interesting. Sometimes a little bit overwhelmed by a lot of information within a single video but it gives you an overview of what is big data modeling and management systems.

It was a good course for beginners of big data modeling. I benefited much from it from the theoretical perspectives.

The lectures and hands on material for this course deserve 5 stars. I did not like the peer review assignment as I thought it was unclear and that the review process is very inconsistent. That being said I have not liked peer review projects for any classes I have take on coursera so I would still recommend this class.

I enjoyed the lectures and liked the topics. Although I would like little bit more hands-on quizes. The "Designing a Big Data Management System for an Online Game" questions where unclear, probably if we had had more hands-on exercises throughout we would not be as confused as gain confidence.

Not as good as the first course in the big data specialization. The big data modeling part of the course was excellent in my opinion because it contained both theory and practice. However, the management systems were not covered adequately, with only one week in the course allocated to cover those topics. I remember how a few management systems are called and what they're good for, but I wouldn't feel confident to perform any practical tasks with big data management systems after finishing this course.
Still, I'd say it's worth taking the course if you want an overview of the most common big data models and management systems.

I got excellent exposure to the various ways that big data is handled and structured and it was in detail as well. I highly recommend this course for anyone who is pursuing a career in being involved in the big data landscape.

Great overview of a few databases and what they are good at. Would have liked actual hands-on like installing a database and demonstrating the key feature the database is good at.

Thx for this course. It helped me in preliminary understanding of the big data modelling world. Fascinating, and intriguing.

All in all the course was very good as the first one. However it is not clear for me what I can do, if I feel myself unfairly graded by my peers at the Peer-Reviews. Furthermore it would be helpful, if the peers had to justify their grading by giving helpful comments to their grades. It is pretty discouraging doing the extra effort, when grading and receiving no constructive feedback at all. Therefore you should be able to challenge grading.

Informative course and video lectures, but final peer graded assignment was lacking clear instructions.

Great course on concepts of Big data modelling.
Great opportunity to learn from 2 people who are actually working on Big data issues in the Live world.
The assignment in week 6 can be improved in terms of more objective questions and the spaces provided to write the answers.
