Introduction

Object-Relational Mapping (ORM) allows you to work with objects and have them saved to the database automatically. It can greatly simplify create-read-update-delete (CRUD) operations and make your code more object-oriented. Under the hood ColdFusion uses the industry leading ORM framework called Hibernate.

Configuration

Application.cfc

Two settings are needed in the Application.cfc file to make an application use ORM: a datasource and ormEnabled set to true.
