Is there a "Universal" access module?

Hi,

(Sorry for the previous misfire)

I'm wondering if there is a module, or set of modules, that allow
a sort of "universal" access to data.

I'd like to be able to do something like :

$spnfile = "file:spn.txt";

or

$spnfile = "db:spn";

or

$spnfile = "mysql:host.example.com:dbuser:dbpass:db:tsble";

I don't mind if I have to write some sort scheme file that
might have :

SPN.scheme-
key - secret - 64
txt - NAS - 28
txt - date - date

so that it understands the format of the text file, db file, or
table.

Thanks, Tuc/TBOH
