DBD::mysql [...]

it does not document if "dbi" in lower-case will be accepted.

A DBD driver only prescribes the dsn-part after 'dbi:drivername:', and the DBI docs do document it; in fact, it actually does not document that uppercase DBI is accepted :-)

DBI connect

It says:

The $data_source value must begin with "dbi:driver_name:". The driver_name specifies the driver that will be used to make the connection. (Letter case is significant.)
update: (@NetWallah's below reply), yes I quite agree.

    So - the documented examples between the DBD and DBI modules conflict.

    However, the code in DBI.pm resolves this conflict - it says:

    sub connect { .... # extract dbi:driver prefix from $dsn into $1 $dsn =~ s/^dbi:(\w*?)(?:\((.*?)\))?://i or '' =~ /()/; # ensure $1 etc are empty if match fails
    so - it will accept EITHER case for the "DBI" part.

    The part about "(Letter case is significant.)" applies to the DBD driver name, not the the "DBI" or "dbi" - it will even accept "DbI".
