Database API for Perl
-- http://www.hermetica.com/technologia/DBI/index.html - DBperl home page Tim Bunce, the author of Dbperl says, "DBperl is a database access Application Programming Interface (API) for the Perl Language. The DBperl API Specification defines a set of functions, variables and conventions that provide a consistent database interface independent of the actual database being used." With DBperl you can access the following databases: Oracle, Sybase, mSQL, Informix, and Quickbase. Plans are currently underway to implement an interface for ODBC.

The cgi-lib.pl Home Page
