Speak for yourself, please.

A conceptual model describes how a piece the world works; you don't
even need a computer to do that. I translate conceptual models into
logical (relational) models to make sure I've accounted for all the
constraints I've found. My target platforms range from SQL dbms to
awk/m4 utilities controlled by shell scripts. I never consider the
target platform until I start accounting for all the constraints I've
uncovered.
