Java EE 6: Develop Database Applications with JPA


This Java EE 6: Develop Database Applications with JPA NEW training explores using the Java Persistence API within the context of a web-based Java Enterprise Edition application, as well as within a stand-alone Java Standard Edition application. This includes using Java Persistence API with the 

Enterprise JavaBeans technology.  

Java EE 6 training takes you through the process of developing Java applications that leverage object/relational mapping with the Java Persistence API. Learn to use the new features and enhancements of 

JPA 2.0.

Learn To:

Update multiple database tables based on relationships.
Perform CRUD operations with JPA in Java SE and EE environments.
Perform data validation using Bean Validation.
Optimize JPA for performance.
Apply transactions and locking.
Map relational database tables to Java using ORM techniques and JPA.
Understand key concepts found in the Java Persistence API.
Create robust entity models.
Create static and dynamic queries using Java Persistence API Query Language.
Create type-safe queries with the Java Persistence API Criteria API.


Course Objectives

Map relational database tables to Java using ORM techniques and JPA
Perform CRUD operations with JPA in Java SE and EE environments
Update multiple database tables based on relationships
Perform data validation using Bean Validation
