(...) it is worth mentioning that, although SQL is
widely recognized as the international "relational"
database standard, [the SQL1999 standard] does not describe
itself as such; in fact, it never uses the term
"relation" at all! (Indeed, it does not use the term
"database" either; instead, as noted in Appendix H,
it talks about something called SQL-data, which is
"any data described by schemas that is uner the control
of an SQL-implementation in an SQL-environment.")

Can anybody tell me the reason for this?
Thanks,
