Hibernate – Java ORM & Persistence Framework

Module 1: Introduction to Hibernate

• ORM fundamentals: object-relational mapping and impedance mismatch
• Hibernate overview: Java ORM framework and JPA implementation
• Hibernate architecture: SessionFactory, Session, and Transaction
• Setting up Hibernate: Maven dependencies and hibernate.cfg.xml

Module 2: Entity Mapping

• @Entity and @Table: mapping Java classes to database tables
• @Id and @GeneratedValue: primary key and generation strategies
• @Column: mapping fields to columns with constraints
• @Transient and @Lob: excluding fields and large object mapping

Module 3: Associations

• @OneToOne: mapping one-to-one entity relationships
• @OneToMany and @ManyToOne: parent-child relationship mapping
• @ManyToMany: junction table mapping with @JoinTable
• CascadeType and FetchType: controlling cascade and lazy/eager loading

Module 4: HQL – Hibernate Query Language

• HQL syntax: object-oriented query language for Hibernate
• SELECT, FROM, WHERE, and ORDER BY in HQL
• Named queries: defining reusable @NamedQuery annotations
• Aggregate functions: COUNT, SUM, AVG, MIN, and MAX in HQL

Module 5: Criteria API

• CriteriaBuilder: type-safe programmatic query construction
• CriteriaQuery: building SELECT queries without HQL strings
• Predicates: WHERE clause conditions with CriteriaBuilder
• Joins and subqueries in Criteria API

Module 6: Caching

• First-level cache: Session-level cache behaviour in Hibernate
• Second-level cache: shared cache with EhCache and Infinispan
• Query cache: caching query result sets
• Cache strategies: read-only, read-write, and nonstrict-read-write

Module 7: Hibernate and Spring

• Spring ORM: integrating Hibernate with Spring Framework
• Spring Data JPA: repositories and automatic query generation
• @Transactional: declarative transaction management with Spring
• Spring Boot and Hibernate: auto-configuration and application.properties

Module 8: Capstone Project and Assessment

• Entity model: multi-table domain model with associations and cascades
• HQL and Criteria API: complex queries with joins and aggregations
• Spring Boot application: REST API with Hibernate and Spring Data JPA
• Final assessment and course certification

Experience in the Industry Gain expertise from Java developers who have used Hibernate and JPA for database persistence in enterprise applications including banking systems, e-commerce platforms, and REST API backends.

Backgrounds at the Top Our Hibernate trainers have worked at Java development teams and enterprise application consulting firms building data-driven applications with Hibernate as the persistence layer.

Clear & Effective Teaching Hibernate architecture, entity mapping, associations, HQL, Criteria API, caching, Spring ORM integration, Spring Data JPA, and Spring Boot auto-configuration are explained with real Java application examples.

Hands-On Learning Focus Students map entities, configure associations, write HQL and Criteria API queries, implement caching, integrate with Spring Boot, and build REST APIs backed by Hibernate through structured hands-on Java labs.

Up-to-Date Knowledge Trainers keep content current with the latest Hibernate ORM releases, Jakarta EE JPA 3.x, Spring Data JPA updates, and evolving Java persistence and ORM best practices.
