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

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

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.

Well presented course providing a wide overview of methods, tools and techniques to collect, analyze, manage and visualize data in big data scenarios.

Very good Instructors. I have learnt a lot. Thanks to COURSERA.

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.

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.

Fairly superficial treatment of a wide variety of topics. There was only a loose connection between some of the hands-on exercises and the lectures. The final assignment questions were not clear and the marking scheme was vague, which led to quite a bit of confusion while answering and grading it.

This is ok. There is some light theory and application of it, but even less hands-on. There is also too much of an emphasis on different big data systems and each brands specific uses. This is good information, but I think it could have been presented on a two page comparison chart. The next course is supposed to be more more hands-on, so I am looking forward to that

I really wish I could give this course more stars, the content is great and well delivered and at a perfect level for someone like me who last worked with big data sets when 20Mb was absolutely enormous and Windows 3.1 was cutting edge technology. But and this seems to run across the whole specialisation, support from the course team varies between very patchy and none at all. Technical questions aren't answered for days if at all.
