Traditionaly in RDBMS theory the ER design is the logical design while
the actual implementation of the tables is the physical design



"Logical design in RDBMS expressed in E-R diagrams"
http://www.cob.sjsu.edu/sadhwa_a/database%20lecture%20Bus%2093.ppt



This agrees with several texts I have packed away at home, but the the
specifics or border between logical and physical design varies by
author.
