Got an amazing introduction to Graph Analytics in Big Data. Technical issues with Neo4J made this course a little more challenging than necessary. But the introduction to Spark GraphX was invaluable.
This course was excellent as an introduction to Graph Analytics and using Neo4j. Not only did I learn a lot, I've been given tasks related to what I've learned in this course after finishing it.

While there is very good content in this course, just like the others in the Big Data Specialization the material is out of date with the tools, there is not enough guidance on the use of the tools, and no one curates the material to keep the directions for using the tools current with the tools. This makes these courses hugely frustrating and a huge time suck without providing insight or value other than how to search the web for answers to fixing all the screw ups in the material.
Over All this makes the course extremely POOR

This course continues the style of the specilization. Wrong instructions, theoretical lecture and inconsiderate course structure. Maybe this course includes too much concepts and skills and students may not be able to command all of them within such a short period of time. I have to say it's a waste of time to download all these softwares in the course.

All kinds of issues with the hands-on assignment software. Sooooooo much time wasted trying to get things running and/ or files loaded etc. This course + specialization MUST be completely overhauled because all of the chosen software models/platforms are much updated themselves, otherwise, just take it down from Coursera altogether!!!

First week of 3 min video. Seriously we want to dive into the subject. And the last two weeks should have more content. Felt like much more copy and paste without understanding why you did that. Understand this should be introduction to Big Data... But the price you pay for the introduction is too expensive.
By Fernando B M•
Full of errors, short of explanations and support, just trying to figure out what to introduce in the command line, not knowing what I am actually doing and why. There are issues reported in the forums eight months ago that have not been fixed. At least one can get a fair idea of what can be done.

Some items are interesting, but the lectures seem goal-less: not enough structure to help understand graph analytics. There's something there but I didn't have much of a takeaway. Introductory material should have more structure.
By Konstantin K•
Most part of materials about Graphs analysis and parallel programming models left unclear despite I have tried to rewatch the lectures some number of times. Previous courses of the spec were clearer
By Julien D•
Many tools... very high level approach.
Complex theory is also explained very quickly and disconnected from the hands-on exercises.
By Manav J•
Not so great content and more theoritical then practical
By Victor C•
by far the most difficult and poor explained.

The things taught is easy and boring

At least, in the previous courses, the instructors were explaining good. This course, for the first three weeks, the instructor is rushing, we would require to pause every minute and see it again. Also the Neo4j has removed the exe file for windows and providing only zip since and year. There is not updates of videos related to that on how to run Neo4j using zip files. Not only on this course, all the courses were still with oldest version of applications. I managed with those applications. But with Neo4j, I can't even proceed with the course. Worst course ever I took. Also I see user who has taken course has posted in Discussion Forum regarding this a month ago and there is no reply for the post from the instructor. My advice is not to take this course at any case.
By William R•
I was unhappy with this. It was clear that this course was pulled together from a superset of other material, and that it was not checked for consistency or completeness. The students were tested on their ability to write down a specific phrase from a video rather than on application of the principles learned from utilization of the graph database tools. (Broccoli -- REALLY???)
Further, the lack of response to questions posted in the forum indicates a lack of engagement from instructors and / or facilitators.

Very interesting topic, but poor course. They totaly kill the oportunity to tech good things.
Tools you need to accomplish are not working all the time and you need to search for the solution in discussion without knowing what are you looking for. I would appreciate whet they give at least some hint what to look for. It could be valuable. Than you just copy paste solution and do not knot what are you doing.
I think deep knowledge what and why are you actually doing will be more valuable than cover every topic.

The material on graph analytics was of introductory level. A string of interesting ideas, with unclear explanations. The lesson on GraphX was basically a copy-paste introduction to it's abilities without actually teaching how to use it. The transcripts are full of mistakes. Someone not proficient in English or hard of hearing would be confused by them. It was somewhat difficult to understand the main lecturer. The best part was the explanation of Neo4j - and it was at an introductory level. A disappointment.

The worst couse I ever take!!
1) week 1-2 is completely useless
2) The whole Neoj4 part is a disaster. You really need to check whether your protocol can still work under the lastest version in windows
3) The GraphX is basically crap. The pipline get stuck from the filtering step as :
[Stage 4:=============================> (1 + 0) / 2]
No FAQ and No debug,
It is irresponsible!!!
By David J R•
This course provides a decent overview of different graphing platforms, however the commands used in NEO4j and GraphX are obviously dated and the instructors have not updated the material in years. The student will spend the majority of their time attempting to troubleshoot problems with the instructions in the hands-on exercises as opposed to learning the content.
By Jian S•
This course is supposed to be the most interesting, and most challenged one of this specialization. However i am quite disappointed with the instructor and the contents he put together. He speaks too fast without much clarity, and worst of all, i can tell most of the time he reads from the scripts without really conveying much knowledge about the contents.

Module 4 was absolutely pointless and terrible. The software was not easy to install and crucial instructions were missing. Additionally, the assignments required working with a dataset of size that was beyond the capabilities of most personal computers.

The last week had exercises run on a Linux VM and, different from the other courses, there were no instructions on installing Virtual Box and the Cloudera VM. I had to get the instructions at the forum, but they should be at the first week readings.
By Armando P•
Sorry but didnt see the point to this course as part of the overall specialization. Maybe as part of the "Load" in a ETL workflow but there would have been other options, better options. Felt it was just thrown in.

Hands-on practice outdated

Poorly guided course!
