JPA [todo]

Quick TL;Dr

• JPA (Java Persistence API) is a specification that lets you define which objects should be persisted, and how those objects should be persisted in your Java applications.

• It is used to persist data between Java objects and relational databases. JPA acts as a bridge between object-oriented domain models and relational database systems thus providing an ORM (object relational mapping) model.

• Persistence is where data outlives the process which created it.

• As JPA is a specification it will need a framework that implements it. Popular frameworks include:

  • Hibernate

  • Spring

  • EclipseLink
