Suppose someone's creating a GUI app (Perl/Tk, etc.) in which the end
user fills in the server, port, user, password, and database into a
screen of some sort. The back-end app will have to know how to
translate that into a DBI connection string. And it's probably not
reasonable to make the user understand the details of how to make a DBI
connection string in this case.
Can I point out that you seem to be assuming the MySQL/Pg model of how
servers, ports, databases, users and passwords work.
This all has no meaning to SQL*Net (Oracle), SQLite, ODBC and probably
other databases, too.
I suspect this is part of the reason that Tim is questioning your
objectives!
