I've also been looking for a single-page "quick reference" PDF for ERD relationship symbols (i.e. "Crows Feet"). I haven't found anything I've liked, so I created this.

I've posted the Full Page, Printable PDF on my blog.

Hope this helps! ERD "Crow's Foot" Relationship Notation Quick Reference

This one is very good explanation:

    I'm looking for a one-page quick-reference or cheatsheet (preferably in PDF) to the meanings of the various ERD symbols in Crowsfoot/Martin notation.

    I've done a lot of googling, but have not found a good, concise quick-reference guide, though I'm sure one must exist.
