This example demonstrates implementing CRUD database operations using  Java Persistence API  for desktop applications.

The Java Persistence API provides Java developers with an object/relational mapping facility for managing relational data in Java applications. Some of the features of JPA are

• You won't have to create complex data access objects (DAO).
• The API helps you manage transactions.
• JPQL is database agnostic, freeing you from vendor-specific code.
• JPQL is portable whereas SQL is not.
• You can avoid SQL in preference to a query language, JPQL that uses your class names and properties.
• You can also use the Java Persistence API for desktop application persistence.

In this tutorial, you will create java client programs to demonstrate the following CRUD operations- Retrieve, Update and Delete operations using Entity clases. The Create operation is covered in Using Java Persistence API for Java SE 7 Desktop applications in NetBeans 7- Part 1.
