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)

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

The spread of the info is good but I think it could need a little more depth.

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

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

some courses lacked a clear explanation. It would be better if the professor talked a bit slower in the videos and had there been more hands-on activities

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.

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

peer review is not good for any assignment.unnecessary delay and of no use.

More focus on theory than practice, but a nice course.

Course material is very good. Instructors are great and talk clearly and explain well.
My only difficulty is with peer reviewed assignments. There is no answer key. So how one grades depends on what he/she thinks is the right answer. I understand there is no easy solution to this problem for online courses. It is not a show stopper though since you can submit multiple times. But why not just grade using Assistant or by instructor themselves.

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

could be a bit more specific, especially for students with a classical DBMS background

Very boring and not interesting course. The slides are just tedious. Additionally, there are some mistakes in week 4 if I'm not mistaken with evaluating weights and coSim(). Many users mentioned in the forums, but nothing has done.

As far as the content is concerned, this is a very good course. Concepts are explained well.
What I disliked about the course is the final peer-reviewed problem.
1. The instructions were unclear about what was needed to be done.
2. When submitting, the HTML of the problem got badly garbled.
3. When reviewing peer submissions, for the first part nobody could read their submission because of the garbled format.
4. Most people did not get the second and third questions right but instead of there being a way to evaluate how much they understood, it was a yes/no option to grade them (which amount to either them passing or failing).
I think this is a promising specialization but the instructors need to pay heed to the bevy of complaints in the various forums.

The material does not delve into enough depth. The syllabus often moves into the next topic just as it begins to break the surface of the current topic. I want more details about the architecture and implementation of each NoSQL database

The course could have mentioned technologies which are more into the market currently and also it would have been better if there were some hands-on exercises on them as well.

The last assignment is really vague and poorly written.
