It can connect to either.see db.connect.

The default is simple DBF, which can use simple SQL support (limited).
Also simple is SQLite but that can understand more/most SQL statements.
MySQL is supported, but apparently there are issues?
PostgreSQL is supported quite well, if I understand correctly.
With ODBC you can connect with Oracle, etc....
