DBIx::Cookbook (http://search.cpan.org/dist/DBIx-Cookbook/) is an extensible collection of modular command-line scripts exemplifying the use of DBI and DBI-based ORMs.
Based on the populated, normalized and documented data model (the MySQL Sakila database), the Cookbook provides fully-working code samples of both creating Perl data models and using them in realistic tasks. The only ORM with a complete set of code samples is DBIx::Class - http://github.com/metaperl/dbix-cookbook/tree/master/lib/DBIx/Cookbook/DBIC/Command/ Other ORMs have been "stubbed" by building their Perl classes representing their datamodel and a single sample command-line script. Rose::DB::Object currently has one example in DBIx::Cookbook: http://search.cpan.org/~tbone/DBIx-Cookbook-0.04/lib/DBIx/Cookbook/Recipe/Searching/fetch_all.pod#Rose::DB::Object as does DBIx::Skinny: http://search.cpan.org/~tbone/DBIx-Cookbook-0.04/lib/DBIx/Cookbook/Recipe/Searching/fetch_all.pod#DBIx::Skinny but many more examples of both (and any other ORM) are requested, either filling out the current problem space, or creating new problems. Git involved! http://github.com/metaperl/dbix-cookbook
