Object Relational Mapping using the Java Persistence API (JPA)
Become a more productive Java developer by leveraging JPA with Hibernate based on best practices.
Description
In this training you will learn to work with JPA. JPA is a standard that describes how we can map Java objects to tables. You start with Plain Old Java Objects which you modify in such a way that the state of these objects can be saved in the database. After this you will get started with relationships, inheritance and queries.
In addition to JPA, you will learn more about the underlying database. You will see that the mapping of the Java to tables in the relational database can be challenging at times. Special attention is paid to best practices around JPA.
In this training you will use Hibernate as an implementation of JPA.
