Re: MV and SQL

I have read the SOFA cards on your site and it seems that some of the
features of a Pick MV system are:
- dynamically typed data
- composed types definable by a regular language
- procedural programming
- persistence of data and procedures/libraries
- integrated development system
- portability
- parsimonious use of computing resources

I don't know anything about the "query languages" of these systems and their
formal semantics.
I'm particularly interested if they offer some kind of declarative query
language.

If you want to compare the "data models" you need to compare the LANGUAGES,
not only the data structures.
