So useful and focus on main basic aspects.

word-choice should have been better...

Good Course covering Modelling systems

Peer Assignment is not too clear

No practical approach for BDMS

Basic for database developers

Nice overview to get into it.

Un poco desactuaizado

Very well explained

it is very helpful

Enjoyed reading

It was fine.

Good module.

good cource

Tool !

Interesting course and valuable theoretical notions. However, i would have preferred that it contains more practical (challenging) tasks especially that most if not all classmates have sufficient IT background and the hands-on were too simple. Moreover, it is easier to understand theoretical knowledge when we apply them in practice. The course creators might have thought to leave all challenging practical work for the final project but i would suggest to include mini-projet at the end of each course. Another point regarding the final assignment of the 6th week, it would have been better to do something similar before it, many classmates and I were confused and unsure about how to answer some questions and we had to evaluate each other's work while being unsure if our own submissions were correct or not.

As far as the content is concerned, this is a very good course. Concepts are explained well.

What I disliked about the course is the final peer-reviewed problem.

1. The instructions were unclear about what was needed to be done.

2. When submitting, the HTML of the problem got badly garbled.

3. When reviewing peer submissions, for the first part nobody could read their submission because of the garbled format.

4. Most people did not get the second and third questions right but instead of there being a way to evaluate how much they understood, it was a yes/no option to grade them (which amount to either them passing or failing).

I think this is a promising specialization but the instructors need to pay heed to the bevy of complaints in the various forums.

This had good information logically presented. However, there are two hands-on activities whose instructions have been out-of-date and incorrect since at least 2016. It is not possible to complete these hands-on activities by following the instructions, and no one on the discussion boards has been able to come up with a solution. The hands-on exercises are very important to allow a learner to reinforce and solidify in their own minds the lessons. Without them, the value of the entire lesson suffers. And if the hands-on exercises are not ever being updated nor corrected for errors, how do I know the other course material is still accurate and relevant? It seems updates to the courses are not made.

Great coverage of the course materials through the readings and lectures. I have given a lower rating because the hands-on exercises did not work for me where the custom Python scripts were needed. The majority of the scripts wouldn't run for me because of dependency failures. Using a VM image specifically intended for the course and scripts, I should not have had this issue. I was able to understand and complete the related exercises by watching the videos for them, but it would have been nice to be able to perform the exercises themselves. Seems like the python scripts were perhaps written by an intern/grad student many years ago. Perhaps it is time to revisit them now that many years have passed.

The course in itself is quite good, although there are many concepts presented in a few videos only.

The bug flaw is the final peer review assignment. Questions are unclear; It is a pain to complete. When reviewing your peers, expect the same issues: you are left alone to interpret if what was done corresponds to what is expected. I guess instructors intended to make something simple but it is definitely not.

And the most frustrating thing is that this has been a recurring complain (see the forum), and nothing has changed so far.

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.

Thanks.

The topics addressed in this course are very valuable and cover a wide range. The presentation of the material unfortunately often misses clarity and sufficient detail. Backup material with a concise treatment and optional readings would be helpful. In addition it would be good to have several guided exercises that train hands-on skills, show practical features and integrate topics. The final assignment fits in this category, it however comes late and as a hike.

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).
