Java Persistence API 2 Development

Expand all

Course Description

The Java Persistence API (JPA) is a standard object-relational mapping (ORM) technology for Java Enterprise Edition applications. This Java Persistence API 2 Development training course takes a detailed look at JPA 2, describing how to map complex relational structures and how to use the Java Persistence Query Language (JPQL) effectively.
