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
