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.
