This was really worse... The content and the exercises have not been maintained or updated.. Especially the most of the software mentioned were really difficult to download and install as they were really out of date...

The exercises required different technologies and there is no explanation in how to install and use them.

In general, the lectures (slides, presentations and videos) are fine, but the practical exercises are not very well made. First, the course is not maintained so the technologies or software used are, for some, not available anymore. Also, the practical exercises are not well describe at all.

Even though I have learned about Cassandra, MongoDB, Neo4j and some other concepts, the proposed exercises need to be rebuilt from scratch.

The questionaires have some problems/errors. Good for learning, not good for "getting a certificate". I a sure they will fix this issues in the future

The instructor knows what she's talking about but is difficult to understand - she speaks quickly with a heavy accent and even the course notes don't always accurately track what she says. The techno-music in the background during the lectures is very distracting - lower the volume or get rid of it.

Finally, you apparently need a computer science degree to install the Apache Cassandra program for Windows as the installation instructions given in the course are wildly outdated - the installation procedures have completely changed since this was recorded. I was unable to properly install this critical program and Coursera was completely unable to help me. This course was a big waste of my time.

It was an amazing experience to take this course. Got much to learn and understand.

great course for beginners! enjoyed a lot..

Very average content

This course does not have much content. You can find most of the content with a quick Google and I don't see why anyone should pay for this. The exercise in week 2 was just a copy-pasting exercise. The exercise in week 3 and 4 are not doable since the data is not given. The exercise for week 5 was great and I enjoyed it. I feel that the exercises for the other weeks should follow the one in week 5. Week 6 just had two super short quizzes. I did not learn much from this course.

just awful.

Se contemplan sutilmente los principales elementos de los temas haciéndolos fácil de entender sin perder de vista la importancia de cada uno.

Interesting course, intersting exercises! Sadly, a bunch of cheating users joined just to submit garbage material as exercise answers.

It was a Great Experience Learning new things related Databases and Definitely Gained Some more knowledge related to database

Ce cours m'a permis de maîtriser tous les contours des données NoSQL ainsi que les logiciels nécessaires.

it is an important course to learn who are interested to do data science

You cannot interact with instructor for any query

You have got great teaching skills.Thank you

great courses must watch it!!!

give my certificate please!!

If was good to learn online
