MORE IGNORANT TRIPE!! Wow, such power. Such articulation. What a masterful command of the language you have. Wow.

So, again, the point I'm trying to make is that applications should be designed in such a way that they are decoupled from the DBMS, as well as from the detailed schema (i.e. the implementation details of the data model)

So have I. I'm not arguing that data modeling should be ignored. I'm not arguing that DBMSs should not be used. I'm arguing that the design of application programs should be decoupled from the details of the DBMS.
