DBIx-Class is an SQL to OO mapper with an object API inspired by Class::DBI (with a compatibility layer as a springboard for porting) and a resultset API that allows abstract encapsulation of database operations. It aims to make representing queries in your code as Perl-ish as possible while still providing access to as many of the capabilities of the database as possible, including retrieving related records from multiple tables in a single query.
ORMesque is an object relational mapper for the Dancer framework that provides a database connection to the database of your choice and automatically creates objects and accessors for that database and its tables and columns. It uses the SQL::Abstract querying syntax, and can also be used as a standalone ORM. It is a great alternative when you don't have the time, need, or desire to learn DBIx::Class.
