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)

Expecting more hands on experience with big data frameworks like Hadoop or Spark. Instructions of the final assignment is very confusing, you don't actually know what it really want you to do until you go through all the Q&As in the discussion forum, which is really wasting time.

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.

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
by Henrique S C•
The content is good, but the final assignment is ridiculous. The instructions are horrible, the peer reviewers are a joke (there are many people there with 0 experience with databases giving wrong feedback), and you don't get the answers for reviewing other people's works.

Very well organized and conceived. By following the course, I was able to learn and build on the concepts with minimal questions or frustration. It taught me what I was looking to learn, was well organized, and well paced. I’m already applying what I learned at work.

The course has a lot of information that is completely useful for BD, I feel that it needs more hand-on exercises. For example, all those BDMS they listed are very useful, but it would have been more practical and fun to teach with an exercise, rather than 50+ slides.

There has been very few on-hands training. It's still very very at an introductory level. At some points it goes very deep, for example with the vectors for a document, but with the rest stay at a very high level. Open an excel sheet can not be considered training ...
by Francisco H•
It was useful but I was expecting more specific exercies and practices with state of the art tools, instead of only a very high level conceptual resume of the frameworks and data types. I hope that in next specialization courses will go deeper into the specific uses.

Far too much time wasted on rudementary material. Maybe coursera wants to strech things out to milk folks in monthly fee. My time is valuable, and this is just wasting too much of it. I'll just buy a book on amazon and cut to the chase.
by Norman L•
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
by Mustafa M•
some of the concept parts were explained in complex manner like REDIS, Aerospike etc etc. The concept must be explained in more higher and logical manner considering this course mentioned no prior experience with bigdata was required
by Saulet Y•
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.
by Kim U•
Unfortunately, some of the videos are boring and difficult to understand, mostly because they fail to present the bigger picture, and through a lack of enthusiasm on behalf of the presenter.
by Sergey K•
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".
by Paul F•
Good ogeneric versight, the excercise of week 6 is not very well elaborated and the peer review instructions/scoring possibilities are not adequate (mostly all or nothing scoring).
by Sai L K•
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.
by Fanny S•
This was my second course of six. It was so theoretical but at the final exam it required so much exercises. I propose enrich the course with exercises and hands on
by Johan S H A•
It was very theorical and not too much practical course, so there are not exercises to understand the BDMS like Redis, AsterixDB, Solr, and the others.
by Aude M•
Very interesting but I struggled with some of the content: the level jumps suddenly, and the course lacks some clear examples of application.
by Konstantin K•
I'm not sure I got the topic Big Data Modeling and Management Systems from material of the course. Quite redundant and dissimilar lectures
by ammar a m a•
Homework's and Assignments are really harder than the course material it self, you need to go to other sources to keep up in my opinion...
by Rizvan N•
The cloudera vm has serious bugs. Please update the OS so that yum works. Could not resolve it so could not do some hands on exercises
by Abhinav S•
The course is not very detailed and misses to explain key concepts. Terminology is used extensively without much explanation.
by Cédric L•
Reasonably good, but less structured and organized that the first course.
I hope the next one will be better on this aspect.
by Ivan S•
IMHO it's better to reduce the scope but provide more details of key technologies. Final assignment is not well explained.
