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)

Peer-graded assignments are bad for multiple reasons. Most important one -- If I'm paying for this course I expect my work will be verified by skilled people, not by other "students".

IMHO it's better to reduce the scope but provide more details of key technologies. Final assignment is not well explained.

I felt there was very little continuity between each of the 6 weeks of this course. Especially in week 1, where I noticed a significant jump in the level of the content and I found the lectures quite vague and ambiguous. But overall I am satisfied. Looking forward to course 3.

The course was okay, but the last Peer-graded Assignment was totally unclear. A lot of other students reported this problem on the discussion forum, but nobody handled this. Some students tried to ask questions, but any menthor answered back in merit. Of course if nobody understand the task then how can we rate each other? It is not fair. I think some examples can help on this problem.

This course offers very useful high level overview of concepts and ideas which make you feel confident in the long run. However, the course is extremely basic and does not go deep beyond the high level concepts. The hands on exercises are boring and do not engage students. The course needs to be improved to make it more useful for students. This course is not very worthy of the money.

A good course taking into account that it does not require previous knowledge. I am giving "only" 3 stars because for a basic (no previous requirements) course I would expect much more additional readings. On the other hand, if you have programming or database experience you will find some topics too "basic".
I have liked it more than the first course on the specialization but I would expect more details (I think general topics are well explained).

Good ogeneric versight, the excercise of week 6 is not very well elaborated and the peer review instructions/scoring possibilities are not adequate (mostly all or nothing scoring).

The course is not very detailed and misses to explain key concepts. Terminology is used extensively without much explanation.

poco contenido práctico

The content is good, but the final assignment is ridiculous. The instructions are horrible, the peer reviewers are a joke (there are many people there with 0 experience with databases giving wrong feedback), and you don't get the answers for reviewing other people's works.

There has been very few on-hands training. It's still very very at an introductory level. At some points it goes very deep, for example with the vectors for a document, but with the rest stay at a very high level. Open an excel sheet can not be considered training ...

Although Content quality was good, the content is too much less and could have been easily integrated to first course or other course in specialisation.
Secondly Quiz were not challenging ,it was just too easy to pass, and this actually takes away the very reason they were employed in this course.

The content of the course is very good, but the definitions and explanations are not straight forward.

Unfortunately, some of the videos are boring and difficult to understand, mostly because they fail to present the bigger picture, and through a lack of enthusiasm on behalf of the presenter.

Homework's and Assignments are really harder than the course material it self, you need to go to other sources to keep up in my opinion...

i think the depth and how it is taught can be worked on. Theres insuffucient coverage to enable us to do the assignment.

The course requires more practical part
By Norman L•

The material does not delve into enough depth. The syllabus often moves into the next topic just as it begins to break the surface of the current topic. I want more details about the architecture and implementation of each NoSQL database

Fairly superficial treatment of a wide variety of topics. There was only a loose connection between some of the hands-on exercises and the lectures. The final assignment questions were not clear and the marking scheme was vague, which led to quite a bit of confusion while answering and grading it.

Definitely could have used more hands on practices. The hands on practice examples could've delved deeper into 'how' instead of just giving you the command lines to run. Majority of the times were spent on lectures talking about abstract concepts. While useful, more of that time would've been better spend on hands-on examples.

1. The course is very general and high level introduction.
2. During the lectures there are some examples that in some cases are presented as very small images and briefly. I personally could not understand some examples presented in week 5.
3. I found the hands-on lectures very helpful. I wish there was more that would delve into more examples in more details.
4. The course was very overpriced given the amount of information offered compared to other courses I have taken at coursera.
