DBI::DBD is a Perl DBI Database Driver Writers Guide.

SYNOPSIS

perldoc DBI::DBD

Version and volatility

This document is still a minimal draft which is in need of further work.

The changes will occur both because the DBI specification is changing and hence the requirements on DBD drivers change, and because feedback from people reading this document will suggest improvements to it.

Please read the DBI documentation first and fully, including the DBI FAQ. Then reread the DBI specification again as youre reading this. Itll help.

This document is a patchwork of contributions from various authors. More contributions (preferably as patches) are very welcome.

This document is primarily intended to help people writing new database drivers for the Perl Database Interface (Perl DBI). It may also help others interested in discovering why the internals of a DBD driver are written the way they are.

This is a guide. Few (if any) of the statements in it are completely authoritative under all possible circumstances. This means you will need to use judgement in applying the guidelines in this document. If in any doubt at all, please do contact the dbi-dev mailing list (details given below) where Tim Bunce and other driver authors can help.
