Troubles when it comes to the student reviwed tasks, sometimes the puntuation doesn't correspond and is very rare getting a right feedback .

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

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

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

Excellently designed course content and organized topics. I like very much the way Ilkay and Amarnath explains on various subjects.

The explanation is very clear. More hands-on coding and practicing should have helped in learning the concept more profoundly.

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

I supposed this course to be more practical, really....

Therefore I am highly appreciative to my teachers and colleagues!

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

There is a lot of useful information in the course but not enough practice to understand it better. And final peer-g

Great course which gives you insights into Big Data Management and various product differentiation used for Big Data

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

Informative course where are you are introduced to

Data Models

Semi Structured Data

Data Lake

Data Streaming

etc.

My only comment is that sometimes I feel that the speaker is talking quickly and the information is not clear

it's pretty good. I learn a lot, but some information is not enough, for example TF-IDF, and vector model

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

Very Good course with rich content - I feel the final assignment could have been better structured.

Some concepts can be simplified by using comprehensive examples.

The course is overall great!

Course is very good, and highly recommended.

More practice on this course will be appreciated

I am totally new to big data. This course give me an immense knowledge about modelling.

Graphs were a bit off and could be better but the overall overview of modeling was good

Great material in this course. But the peer review assignment is a little bit weird...

I enjoyed this course, the topics was more clear and deep in contrast with level 1.

Should have more and better explanations of various topic like vertica, astersikDB

Very nice explanation of different data models and Big Data software applications.
