We've determined through the CB that he wants to access the data from gzipped files on Unix. DBI won't help, you'd need something like Parse::Access which doesn't AFAIK exist yet.
Any reason why you can't get the files to a PC with Access on it, then use DBI/DBD::ODBC or Win32::ODBC? Or export the data to a delimited or other format? Maybe even write a script to unzip the files and Net::FTP them to a Windoze box with Access on it? Automate any necessary commands on the Windoze box with Net::Telnet or maybe Expect (I've never used Net::Telnet, but it looks like if you use it you don't need Expect...)?
