Variable Declarationby ant (Scribe)

ant has asked for the wisdom of the Perl Monks concerning the following question:
Any advice is gratefully recieved.
My problem is that I have a small database, with about
15 scripts accessing the database using Perl DBI.
Should I declare the database, username and password as
variables private to that script using my $database = 'live' etc.
This would mean that any changes to the database would mean
me visiting each script and changing the code.
OR should I create a package and declare the variables there
and then export them into each script.
This would then mean they are global variables, but at least
I only have to visit one file to change the details.
OR should I create a functions file, that is used in the main
script with a sub routine called get_db_details (and declare
the variables there) that would then return the details of the
db into variables in the main script.
This again would mean that I would only have to access one
file to make changes.
