Course content clear and concise- but assignment directions were too open to interpretation. Also presentation of the assignment results for review where the answer was requested in table format the table overrides the scoring section and the visibility of the responses appeared scrambled. Peer review on week 6 assignment needs a rethink-this need some process of challenge where a mentor or instructor can intervene to correct faulty peer reviews

It's too superficial and the required skill level and required background knowledge is changing from video to video. Especially the walkthrough of different named database systems, was to deep, and I didnt get much out of that. I was like if you just like trying to teach me how to operate my tv by walking through the complete manual from start to end. I was often wondering, how is this relevant in this module...

My primary concern with this course are the mentors and the final assignment. The final assignment was particularly vague in exactly what it wanted and when asked on the forum, mentors would respond with comments like "you should just understand it." The mentors through each week were altogether unhelpful and that culminated in a vague final assignment with little way to understand it without a bit of guessing.

The course content was not very appealing. Explanations were not that engaging. What I really missed was the actual practical aspect where you don't work with command prompt but an much more user friendly interface that is more up to date with current standards.

Final task has numerous problems ranging from Coursera site formatting limitations that have not been accounted for to lack of master-answer to peers (e.g. peers unfamiliar with industry can't grade what they don' know)

Tedious exercises through VM where instructions oftentimes do not work out of the box. It is a hassle to download the slides in small sets and their design awful. Definitely one of the worse courses I have taken.

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 material seem buggy. I cannot proceed in the exercise.

Too simple, no programming, just theory.

Very basic and lack real time

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.

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.

Course instructors show no interest in answering questions in the forums regarding technical issues that students are having running the systems required to complete the course. There are unanswered posts from several months ago.

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.
