I don't think that's right. Databases have been around since the 60's, 
Codd's paper was in 1970, neither is the presentation of the data on the 
screen as tables, linked detail tables, editing etc in forms. QBE was 
another IBM invention in the mid 70's. Hard to see how your data model 
would change because of the presentation logic. Different programs might 
do things slightly differently but the end result is surely more of the 
same?
