"El presente curso oficial de Oracle está diseñado para otorgar a los participantes una base sólida en el uso de Java Persistence API para simplificar el desarrollo de la capa de persistencia dentro de sus aplicaciones en las plataformas Java SE y/o Java EE.





JPA es una abstracción sobre JDBC que permite realizar un mapeo ORM entre un modelo de negocio orientados a objetos y un modelo relacional de forma sencilla, realizando toda la conversión entre los objetos y las tablas de una base de datos. "
