I'm not going to defend the RDBMS engines or the SQL standard.  I
partly blame Ted Codd for not paying more attention to the way the
gang down the hall was designing SQL.  I also blame the CIA for
adopting an early version of SQL (as specified in the IBM Journal
of R & D) and sending out a BAA for somebody to implement it.
Oracle bid for it.  IBM didn't.    (02)

Two points I will defend:  a clean logical foundation, and appropriate
locking methods to ensure data integrity during updates.    (03)

Despite its quirks, the SQL WHERE clause supports full FOL.  SPARQL
doesn't.  For data integrity, you need some kind of "silo" to ensure
that the DB constraints are preserved during updates.    (04)
