I think the term you were looking for is "projection".


I have already renamed parameter from "surjective" to "injective".
But I am ok to do do one more renaming to "projection" if it will be considered as better alternative. From my point of view, "projection" seems to be clearer for people without mathematical background, but IMHO this term is overloaded in DBMS context. The irony is that in Wikipedia "projection" is explained using "surjection" term:)
