Anyone have any interesting ER diagrams to learn from?

Question

Maybe stackoverflow can release theirs?

:)

Answer 1

Try searching google image for erd

Answer 2

I've tried but most aren't practical. An example of a good one is the vbulletin database schema. Optimized database schemas won't be in BCNF they will have optimizations scattered about that will reduce the number of queries.

Answer 3

There's a Library of Free Data Models that I find quite impressive. You can find one or more model examples from many different areas in there.

Answer 4

Try The Data Model Resource Book by Len Silverston. It has 3 volumes and not only shows but also explains the usual use cases for ER diagrams.
