Object-Relational Mapping

  • Antonio Goncalves

Abstract

In the previous chapter I went through the basics of object-relational mapping (ORM), which is basically mapping entities to tables and attributes to columns. I also introduced configuration by exception which allows the JPA provider to map an entity to a database table using all the defaults. But defaults are not always suitable, especially if you map your domain model to an existing database. JPA comes with a rich set of metadata so you can customize the mapping.
