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)

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 However, there are two hands-on activities whose instructions have been out-of-date and incorrect since at least 2016.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.
