Our Hibernate training course will give you hands-on experience of configuring and deploying Hibernate-based Java web apps, delivered by our expert Java instructors.

Hibernate is often found in the wild alongside the Spring framework, where together they are able to deliver responsive Java web applications with full Model-View-Controller (MVC) and Object Relational Mapping (ORM) capabilities.

Hibernate deals chiefly with Data Persistence – for instance controlling User Sessions on busy e-commerce sites, and can be used alongside or as a replacement for other Java / EJB data persistence methods.

• Hibernate Architecture
• Hibernate Query Language (HQL)
• Object Relational Mapping (ORM)
• Working with Persistent Objects
• Mapping Annotations & Associations
• Mapping Inheritance
• Spring and Hibernate Transaction Management
• Performance & Tuning Optimisation
• Locking Best Practices

Java developers who are looking to utilise the Hibernate Framework to perform powerful Object Relational Mapping activities and query databases using Hibernate Query Language (HQL).

Good hands-on coding experience in Java and an understanding of how Relational Databases work.
