Exactly. :-) It's problematic to view the evolution of data modeling in the same way as the evolution of programming languages or paradigms associated with programming languages (including SQL). So while languages and language-oriented paradigms that assist in abstractions (e.g. OOP) have changed a lot over the last few decades, the concept of data abstraction and modeling (relational data modeling in particular) has seen less dramatic evolutionary change. I wonder whether this in itself makes it the reason why some folks believe there ought to be a change from an ostensibly outmoded and antiquated paradigm! Great Frege's ghost indeed!!
