Way back in 1982, when I learned my first relational database system, the
presentation always began with
"what are the services you expect from a DBMS". And the comparison was always between the new (at that time) relational product and the tried and true product based on CODASYL DBTG.
Twenty years later, it's a very different world. People create databases as casually as they used to create files, and with just as little thought. With a small investment, and a low level of mission criticality, a database just doesn't represent the same thing that it did twenty years ago.
And therefore axioms that I carry around, embedded so deep that I am no longer conscious of them, are not the same as your axioms. Just as you and I have a slightly different take on whether "pepperoni and onions" is the same as "onions and pepperoni" or not, so likewise, we have a different take on the TCO of building a low investment database.
