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)

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.

Great coverage on data models, however the online scenario was little too extreme for me - esp. not coming gaming or digital background.

Excellent intro to the subject. The instructors explain the material well. I deducted one star for the grading treatment of the Peer-Graded Assignment (Catch the Pink Flamingo). It's understood that there is no one "right" answer, but peers should be given a range of possible answers.

I felt the assignment was a bit confusing, however, it was good to see how others responded to the same questions.

Nice diversed lecture, only the slides could be more visually appealing and the maths involved could be deeper. Gives good overview on the subject.

This course is a valuable introduction to Big Data Models and Management Systems for a variety of data types. The hands on exercises and company use case examples provide helpful context and application of the concepts. This knowledge also provides the learner with more confidence in navigating big data conversations in a professional environment.

Great course where I was introduced to lots of new technologies, would like to apply them in practice. Would be nice if there were more hands-on exercises.

The course was very informative. One suggestion would be to include more practical exercises as it would help in internalizing the concepts better.

This course captures the overview of Big data modelling concept in a very simple way. I found this course very useful. Instructors are good to explain the concepts. Though it would be good to add one or two (add-on or optional hands on exercises) handson for graph and tree data modelling.
