If Java is used for enterprise class applications, accessing relational data in an effective way, the use of a good persistence framework is a very important. The Hibernate framework offers a complete object-relational mapping solution to this end. Hibernate makes use of the standard Java Persistence Architecture (JPA) of the Java EE platform.

In this course, we will:

• explain how OR mapping works with Hibernate and JPA
• discuss the implementation of the CRUD methods
• use native SQL, HQL, JPQL and criteria queries
• dive into the use of transactions

• Overview of Hibernate and the Java Persistence Architecture (JPA)
  • O/R mapping • Hibernate architecture
  • Java Persistence Architecture: annotations • mapping • entity manager
• Hibernate configuration
  • SessionFactory • JDBC connections • logging
• Persisting objects
  • Persistent classes • components • relations • inheritance • collections
  • Different mapping options • n-n associations
• Querying
  • Criteria Queries • HQL (Hibernate Query Language) • JPQL • native SQL
• Caching • transactions and concurrency • performance

Lecture and hands-on exercises. The participants will work with Java applications accessing IBM Db2, Oracle, MySQL, MariaDB, PostgreSQL, or other databases.

Delivered as a live, interactive training: available in-person or online, or in a hybrid format. Training can be implemented in English, Dutch, or French.

Knowledge of Java programming (see course Java programming) and relational databases (see course SQL and relational databases fundamentals) is required. 

Architects, designers and programmers who are interested in object-relational mapping, using Hibernate and JPA.
