ORM for existing projects using Phrasebook

Just few questions came in mind so I thought to get some expert advice. Well, I am not an DB expert but comfortable with SQL/Perl DBI and can write queries using Phrasebook. I mostly use PostgresSQL DB. As there is a lot of discussion of ORM and many new implementations are coming using ORM techniques (e.g.; DBIx::Class etc) for DB interaction so just wondering how can I use ORM in my existing projects as I am still using DBI + Phrasebook and what benefit shall I get if I switch to ORM?

Thanks for reading!
