Dbi2 will be based on jdbc , you can watch and test the examples from here
http://svn.perl.org/viewvc/modules/dbi2/trunk/JDBC/


I came to the conclusion a year or so ago that rather than try to create
a new Driver API from scratch we should simply adopt an existing one.

The most widely know object oriented database API that's a close fit to
the DBI's needs and most database client APIs is the Java JDBC API.
It's also suitable as a Parrot API, which is a key goal for DBDI.

So I'm specifying that the DBI->DBD API will be based closely on JDBC.
How close? Very close. Specifically, closely enough that we can refer
users JDBC documentation and only document differences and (inevitable)
extensions.
