This course teaches students how to build, develop, and run Java applications that use the Java Persistence API (JPA). Students use IBM Rational Application Developer V7.5, which provides complete support for the JPA specification, to develop the JPA-based applications in this course.
JPA provides a mechanism for managing persistence and object-relational mapping. It represents a significant evolution over previous persistence techniques, such as Java Database Connectivity (JDBC) and EJB 2.0 Container-Managed Persistence (CMP), and it can be used in both Java Standard Edition (Java SE) and Java Enterprise Edition (Java EE) applications. �
This course begins with an overview of persistence and the JPA specification, including features of the Java Platform that support JPA and JPA architecture. Subsequent topics include creating JPA entities, using Java Persistence Query Language (JPQL) and performing object-to-relational mappings (ORM) for persistent data. Students also learn how the use of JPA in applications differs between the Java SE and Java EE environments.
Hands-on exercises throughout this course give students practical experience developing JPA-based applications with IBM Rational Application Developer V7.5. JPA development skills covered in the exercises include creating entity classes, developing a Java SE application to perform database operations, mapping entities to single and multiple tables, and working with JQL queries.
Note: This course covers the use of JPA in Java Standard Edition and Java Enterprise Edition Web container environments. It does not specifically address the use of JPA with Enterprise JavaBeans (EJBs). To learn how to use JPA entities running in an EJB container, students should attend one of the following courses:
This intermediate course is designed for experienced Java application developers who want to learn how to develop Java SE or Java EE applications that access relational data using JPA
Before taking this course, students should have practical experience with the Java programming language. This knowledge can be gained by successfully completing one of the following courses:
Students should also have knowledge of database concepts such as SQL, primary and foreign keys, joins, and referential integrity. Experience using JDBC is beneficial.
Some knowledge of Java EE Web development and experience using Rational Application Developer or another Eclipse-based development environment are also beneficial.
There are no follow-ons for this course.
