Its a programming language is my humble opinion. One has to 'code' in
it. It has a defined syntax and it has a rather large and complex
overhead.  By the way, I also think BASH is a programming language.

One never ever hits the button for every little action, does one ? My
latest data entry form takes 20 separate sets of entries before the user
clicks SAVE.

Golly. I grew-up in real computers. Relational databases are simply
database structures, linking records. There is no reason to use joins
and views IF the database is carefully planned. Joins and views are
another overhead. Rule Number 000001 in programming is Keep It Simple.

Index-sequential is another database access method that came along. Very
useful. Access random is another. Data is actually 'flat'. It can not be
anything else. However additional retrieval by non-primary key is
usually desirable. Traversing chains of linked records is another method
too.

I've done several domestic and international contracts writing
applications using relational databases. Are you more of a Sys.Op than a
computer programmer / systems analyst / systems programmer / database
designer / systems designer ?

When SQL first came out, I think it was an IBM thing, I never liked the
syntax. Years later I'm using it effectively and very productively.

Thank you. Thank you too for your interesting comments.
