Just definitions after definitions, the background music is distracting.

I have given up on this course, as the content is too academic and mechanical in nature. Definition after definition, with little practical guidance on how to *design* good databases for real-world use.
The quizzes and assignments are terrible - sorry, just telling it as I see it. The sequence of topics and assignments doesn't flow. For example, why are we shown a Sybase modelling tool, that doesn't use Chen notation, but the preceding video and subsequent assignment use Chen's?
Only academics use Chen's original notation - anything real world has far too many entities/attributes for this notation to be usable. Also, none of the tools that I've seen out there use this notation for that reason. Crow's foot or IDEF1X, or even UML; never Chen's.
On the other hand, the style of presentation in the videos is engaging, rather than the usual voice over powerpoint with varied settings, and a lot of well thought out animated examples. A shame that it just doesn't fit together well and focuses too much on academic concepts and not real-world practice.

I am sorry, but I cannot say anything positive about this course.
The course flies over the topics addressed
Explanations are extremely vague, so that one has to constantly look for external information
The tasks have errors and they do not use the software required for some assignments
The english spoken is incomprehensible
The course staff has not commented any of the discussion threads. If you have a question, do not count on any help by the course provider
