I'll have a go, then: Analysis is taking something apart (to see how it works). Whereas design is putting something together (to make it work). :)

No. Nothing that covered analysis /thoroughly/, at least, and certainly not /formally/. I've learned a few diagramming notations in my time, but I've never had analysis presented as a science as opposed to an art or craft.

I have a database of currently 102 relvars with in total 590 attributes. No formal analysis, whatever that means. I drew some pictures in the beginning for communication, but once I had a prototype, it was simpler to just show, tell and ask. People understand tables just fine. What do you mean, "What happened after that?"
