Object-Relational Mapping is a method of mapping a relational database to a class structure in an object-oriented programming language. In simpler terms, it takes your database structure and creates an interface that keeps you from having to write any SQL at all. Not only does it abstract the database, it abstracts the relational portion as well, making it simpler for you to work in an application.
