I use both the Oracle RDBMS, inclusive of the database versions: 7.0, 8.0, 9i, 10, and the Mysql RDBMS 4 and 5. While I've used other database engines, these two cover the ground comprehensively and are about the best there is - IMHO.

This is also the home of the following Oracle interface code written in Perl:

oradb	Command-line interface (prototype) to the server-side Oracle PL/SQL debugger.
Oracle::Debug	Perl module to interface with the PL/SQL debugger package DBMS::DEBUG.
Oracle::Trace	Perl application to parse Oracle trace files.
