Re: SQL1999-standard makes no reference to term "relational" - why?

Celko will probably know for sure, but my guess is that the SQL standard is a specification for a computer LANGUAGE, and that language is used to communicate with computers that contain "any data described by schemas that is under the control of an SQL-implementation in an SQL-environment." But, that's just a guess...
