DBI is indeed a database independent interface; and indeed none of the perl usage you cite will change for different DBMSs (although there may be special methods for different DBMS's for truly radical variations only).

The only thing that can change for your purposes is the SQL you send to the DBMS as a string, whose syntax may indeed vary with DBMS.

For further information take a look at DBI::FAQ
