Not an *exact* look-alike, but it seems like it would have quite a few 
things in common with it--UML being a distant descendant of ERD 
notations and such.

Descriptions of ER representations in UML reference books are amusing:  
"If you need to represent x in your ER diagram, use a tagged value.", 
which always seems to the engineer in me like:  "We know the UML is too 
general to unambigously represent your actual RDBMS data structures, so 
here's a clumsy work-around."
