| The Java Persistence 2.0 API (JPA 2.0) is a specification |
| for the persistence of Java objects to any relational |
| datastore. This document provides an overview of JPA 2.0. Unless |
| otherwise noted, the information presented applies to all JPA implementations. |

| This document is intended for developers who want to learn about JPA |
| in order to use it in their applications. It assumes that you have a strong |
| knowledge of object-oriented concepts and Java, including annotations and |
| generics. It also assumes some experience with relational databases and the |
| Structured Query Language (SQL). |
