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.
