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)

All in all the course was very good as the first one. However it is not clear for me what I can do, if I feel myself unfairly graded by my peers at the Peer-Reviews. Furthermore it would be helpful, if the peers had to justify their grading by giving helpful comments to their grades. It is pretty discouraging doing the extra effort, when grading and receiving no constructive feedback at all. Therefore you should be able to challenge grading.

Overall a good course to get the basics of what the difference is between managing Big Data system, versus your more traditional systems. I really like both instructors.
I took one star off because one of the twitter API assignments that we were supposed to do in the VM didn't work. Plus there's no one to support you in case an issue like this occurs.

This course is a valuable introduction to Big Data Models and Management Systems for a variety of data types. The hands on exercises and company use case examples provide helpful context and application of the concepts. This knowledge also provides the learner with more confidence in navigating big data conversations in a professional environment.

I loved how it built on knowledge obtained from the previous course and even had a recap video as a reminder of what was covered then. My only real gripe is how the felt like a bit of a curved ball - it was tricky to understand what was required of us. Overall, the course content is solid and I would recommend it to anyone
The lectures and hands on material for this course deserve 5 stars. I did not like the peer review assignment as I thought it was unclear and that the review process is very inconsistent. That being said I have not liked peer review projects for any classes I have take on coursera so I would still recommend this class.
par Prospero-Martin R•
I enjoyed the lectures and liked the topics. Although I would like little bit more hands-on quizes. The "Designing a Big Data Management System for an Online Game" questions where unclear, probably if we had had more hands-on exercises throughout we would not be as confused as gain confidence.
par Carsten K•
The course is great, but the peer review assignment at the end needs a lot of polishing, as the instructions are unclear and way to vague. Furthermore, the answers are not very specific, making grading difficult at best. Despite the peer review assignment, I can fully recommend the course.
par Koyel G•
This course captures the overview of Big data modelling concept in a very simple way. I found this course very useful. Instructors are good to explain the concepts. Though it would be good to add one or two (add-on or optional hands on exercises) handson for graph and tree data modelling.
par H J•
Excellent intro to the subject. The instructors explain the material well. I deducted one star for the grading treatment of the Peer-Graded Assignment (Catch the Pink Flamingo). It's understood that there is no one "right" answer, but peers should be given a range of possible answers.
par Devon E•
Another excellent course.
The only thing I would have liked (and maybe this comes later in the upcoming courses) is for the course to take a look inside the python and Lucence scripts so that we could be talked through how these are actually processing the data with guidance.
par Vinod S•
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.
par Sarah A•
I believe some of the content is not easy to understand, although the course is great, I had to go online to check some of the concepts to fully understand them.
Still, I recommend the course for all of those initiating their careers with Big Data
par Dhairya T•
Pretty good course with deep learning methods and detailed hands on experience except the Gephi one where they could have mentioned better about the downloaded gephi icon on desktop wont work. But overall an excellent course ..worth your time
par Felipe A Z•
The course is better than the first one, which more real examples and tools that are used to model and manage big data. The concepts are getting more intersting because they are more related to the real activities with big data.
par Dennis N•
I got excellent exposure to the various ways that big data is handled and structured and it was in detail as well. I highly recommend this course for anyone who is pursuing a career in being involved in the big data landscape.
par Snehal B•
I would rate it 4/5.
First 4 weeks, we can still relate and keep up to pace with context. But week 5 onwards it becomes difficult to understand. Please come up with more real life scenarios to explain different BDMS models.
par Apurva T•
Course was very good, some concepts were a little tough to understand, like the graph network and other topics of first 3 weeks. But on the whole a very good course to understand basics of data modeling and management.
par Xing Z•
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.
par PLN R•
Pretty good course. The peer corrected assignment is avoidable. Instead, a little bit of programming may be introduced! The course becomes extremely boring due to only theoretical aspects and quizzes.
par David R D N•
Pretty good overall, although some exercises are a bit difficult to understand from the descriptions and instructions given, some graphs and initial reference documentation for exercises might help
par Yaniv G•
Overall relevant and clear presentations. Course material quite general, but I guess this is expected from an introductory-level course.
Peer-reviewed assignment's instructions can be clearer.
par Bhola N R•
It was a difficult module, although trainer tried to convey but seems it is more complex it took time for me to understand the concept and apply the same while doing my assignment.
par CHANDAN J•
Great overview of a few databases and what they are good at. Would have liked actual hands-on like installing a database and demonstrating the key feature the database is good at.
Interesting. Sometimes a little bit overwhelmed by a lot of information within a single video but it gives you an overview of what is big data modeling and management systems.
If you have the fundamental knowledge of database and json, the only valuable videos for you are in week 5. As it says in next course(course 3), the course 2 is not required.
