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)

Lectures are not really useful for real examples. Indeed final task related to the graphs is not explained in the lectures about how to declare properties for nodes/edges in a graph.

Compared to the first course this one is not as good, especially Week 5. You can see lots of people complaining about week 5 which does not make sense to the students at all.

Slides were minimally helpful, lectures did not track well with quizzes, assignments were poorly designed and difficult to imput into the tool.

Disappointing course. Poor language level, many mistakes (grammar, words, in examples shown). Poorly explained and confusing final assignment

Level of content between week four and five is vastly gapped. Too big of a jump. No explanation of BDMS and DBMS in between

Too high level. Last assignment too ambiguous, peer assessment was completely random and not reliable to pass the course.

The final assignment has barely any relation to what is actually taught. The course does not really prepares you for each. Or you previously knows how to do it, or you have to search for other sources and find out in other courses and foruns. The course is essentially an intro of an intro of everything it tries to teach. It does not teach you how to really use anything useful for work or study. They only present and say what some tools can do. Very very superficial course. It opens to many fronts. It should be named "An Introduction to General concepts and tools of Big Data management".

The cloudera vm used by the course requires login credentials (which students do not have) in order to correctly update and install the software using the commands given. Looking at the forum, there have been problems with software updates for quite some time, but as of Feb this year students are unable to do the updates needed outright per https://docs.cloudera.com/documentation/enterprise/release-notes/topics/cm-retrofit-auth-downloads.html. The short version, you will notice you are asked to use librasheets and will how no ability to do so.

Coure appearst to be abandoned by instructors (as of 02/2022). Practice material is extremely outdated, relying on a VM with CentOS 6 that can no longer correctly install packages. The exercises appear to have been last updated in 2018 and despite multiple questions on the forums I haven't seen any recent feedback from moderators or instructors.

The state of this course is unacceptable for anyone not familiar with troubleshooting LInux. The software is woefully outdated. I do not recommend this course until the instructors apply the needed updates. Coursera should probably remove this course, considering it's a paid service.

hard to follow not because it is difficult, but the lecture is only slides, texts, reading slides, very boring and not so many hand-on instruction. only thing i remember is the instructor's face after finish this class. Dont know why you add this into such a good specialist.

Poorly designed assignment on data modeling did little to expand my knowledge on the topic. Which is a shame since the individual lectures were well done and very interesting. The "Pink Flamingo" peer-peer-reveiwed exercise needs to go.

The last peer review is really hard to do. Hard is because the wording is very ambiguous and not all understand how to review. There was a guy who answered with SQL query. This is hardcore since we have not learned that yet...

Maybe this course would have made more sense at the end of the specialization. But here it just seems like an unnecessary spike in difficulty to understand (not necessarily difficulty to pass) due to the poor lecturing style.

As a manager in an IT consultancy, I can't justify sending my personnel through this course, even at $69 per course. The amount of information gained is very thin and does not move one toward being productive.

The content is only intended for people who have a background in this field. The peer graded assignment is completely unclear on instructions . the test is not at all well devised. I am regretting.

constant problem during every exercise, Prepare to spend more time troubleshooting virtual machine problems and CentOS 6 issues than learning about BIG Data

Disastrous set-up of grading assignment. Waiting for 7 days to get rated. No possibility to contact any Coursera staff directly.

Boring, impractical, very broad, 4 years out of date. Trains you on a bunch of clunky definitions but no useful substance

Course material is very poor and did not give much support for doing assignments.
