JPA and Hibernate - 3 days Online Classroom

JPA and Hibernate - 3 days Online Classroom

Master Java Persistence API (JPA) and Hibernate to build robust, scalable, and high-performance data-driven applications. This hands-on course teaches you how to simplify database access by mapping Java objects to relational databases using industry-standard persistence frameworks.

Through practical exercises, you'll learn entity mapping, object-relational mapping (ORM), relationships, queries, transactions, and performance optimization using JPA and Hibernate. You'll also explore advanced features such as inheritance, caching, validation, and fetching strategies to develop enterprise-grade Java applications with confidence.

By the end of the course, you'll be equipped to design, develop, and maintain efficient persistence layers for modern Java applications using JPA and Hibernate best practices.

FAQ

When is the class held?

The majority of the class is a full-day online course from morning to afternoon CET with 8 hours / day straight. However, please contact us to confirm the final detailed schedules.

What is JPA?

JPA (Java Persistence API) is the Java standard for object-relational mapping (ORM), enabling developers to map Java objects to relational database tables.

What is Hibernate?

Hibernate is the most widely used implementation of JPA, providing advanced ORM capabilities, performance optimization, caching, and database portability.

Do I need prior Hibernate experience?

No. However, participants should already be comfortable with Java programming and have a basic understanding of relational databases and SQL.

Will I learn through practical exercises?

Yes. The course includes hands-on labs that allow you to build entity models, write queries, manage relationships, and implement persistence features in real-world Java applications.

Will this course prepare me for Java enterprise roles?

Yes. You'll develop essential enterprise Java skills including object-relational mapping, entity management, HQL, JPQL, and performance optimisation, which are widely used in backend development.

What skills will I gain?

You'll learn to design efficient persistence layers, map complex entity relationships, build database queries, optimize application performance, and apply JPA and Hibernate best practices in enterprise development.

Can these skills apply beyond Hibernate?

Yes. Although the course focuses on Hibernate, the JPA concepts and techniques are transferable to other JPA-compliant providers and enterprise Java projects.
