I would be particularly interested in any suggestions towards improving the documentation, correcting any Perl-version or platform dependencies, as well as general feedback and suggestions.


See DBIx::DBO2::Record, DBIx::DBO2::Fields, DBIx::DBO2::Table, and DBIx::DBO2::TableSet for key interfaces within this framework.

See DBIx::SQLEngine for information about the underlying database interface.

See DBIx::DBO2::Comparison for a a review of where this framework fits into the spectrum of numerous other modules on CPAN that provide alternative systems to map objects to and from SQL databases, including Class::DBI, Alzabo, and Tangram.
