<h1>Understanding Java Persistence API</h1>
<p><a id="sthref25" name="sthref25"></a>The Java Persistence API (JPA) part of the Java EE EJB 3.0 specification, simplifies Java persistence. It provides an object-relational mapping approach that lets you declaratively define how to map Java objects to relational database tables in a standard, portable way. JPA works both inside a Java EE application server and outside an EJB container in a Java Standard Edition (Java SE) application. An application written according to the JPA specification is scalable, transactional, and secure.</p>
