SQL = Structured Query Language. It's connected with databases only by 
coincidense, just like any UNIX OS could have apps written in Pascal 
rather than C.

There's also ANSI SQL. Most (all?) RDBM's servers implement a superset 
of the required parts of the language, and the various dialects all use 
the same "grammar". Not all the big ones implement all the optional 
parts of the ANSI SQL (MySQL f.e.).

That would be the tabular datastream protocol (TDS, as in FreeTDS) which 
is also used by Sybase database servers. That's why the perl module 
DBD::Sybase also can be used to access MS-SQL servers if it's built 
against the FreeTDS libs.
