in reply to What CPAN modules are "good reads"?
DBI is my favorite. The
book came from that documentation.
Its docs include also a roadmap.
For other monks' opinion, see Looking for Mr. Good Documentation!.
DBI is great, but it's source can be hard to follow at times unless you are willing to dive into the XS code, and DBI::PurePerl is not a complete DBI implementation and so somewhat hard to follow too.
However, that said, if you can manage to get your head around DBI you will certainly learn a lot.
