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)

The content is good overall, but the final project assignment is awful. It's not about whether the questions are too easy or too hard, it is the way in which the assignment is organized that seems confusing.

This material in this course seems to be based on a belief that the student has significantly more knowledge than assumed for the first course in the Big Data series. Because of this unfounded assumption, without regard to explanation, I have marked it down to four stars vice the five for the first course.
I think by providing the student with an adequate background, or additional resources, this course could easily be ranked as a five-star course.
In short, for no apparent reason, it quickly becomes more difficult than the first course; and instead, I wish it had been more of a natural transition from the first course.

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

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

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.

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

The final test has little to do with the course. You must do extra study to respond.

Hands on practice needs to do a better job

The topics addressed in this course are very valuable and cover a wide range. The presentation of the material unfortunately often misses clarity and sufficient detail. Backup material with a concise treatment and optional readings would be helpful. In addition it would be good to have several guided exercises that train hands-on skills, show practical features and integrate topics. The final assignment fits in this category, it however comes late and as a hike.

Interesting course and valuable theoretical notions. However, i would have preferred that it contains more practical (challenging) tasks especially that most if not all classmates have sufficient IT background and the hands-on were too simple. Moreover, it is easier to understand theoretical knowledge when we apply them in practice. The course creators might have thought to leave all challenging practical work for the final project but i would suggest to include mini-projet at the end of each course. Another point regarding the final assignment of the 6th week, it would have been better to do something similar before it, many classmates and I were confused and unsure about how to answer some questions and we had to evaluate each other's work while being unsure if our own submissions were correct or not.

The course is great. The final peer-reviewed project is interesting, but very badly designed. The explanations are fairly confusing, and the peer-reviewed format really doesn't fit this assignement, as modeling can be performed in many different ways, that untrained peers might not recognize.

I feel the assignments were a little vague and such assignments should be reviewed by mentors and not just fellow colleagues. Also, the concept on which the questions were based, were not covered that widely.
Additionally, if someone wants to refer to the slides in future they should be able to get the information they want from the slides itself, so they could be made more descriptive.

The course takes a broad approach to the subject.
What I miss: the study material should provide more and better organized (theoretical) information (e.g. on topcis like database design, data structures, etc.)
What I like: presenting of current software projects around big data

Good information overall, but the "peer graded" assignment at the end is poorly designed and seems unnecessarily arbitrary. Not a clear value add over a "final exam" format to justify waiting days for someone to "grade" your work. Instructions for this assignment are poorly written and unclear - for example, completely NOT clear you are asking us to identify a primary key versus stating there is no primary key, etc.

Peer-graded assignments are bad for multiple reasons. Most important one -- If I'm paying for this course I expect my work will be verified by skilled people, not by other "students".

IMHO it's better to reduce the scope but provide more details of key technologies. Final assignment is not well explained.

I felt there was very little continuity between each of the 6 weeks of this course. Especially in week 1, where I noticed a significant jump in the level of the content and I found the lectures quite vague and ambiguous. But overall I am satisfied. Looking forward to course 3.
