JPA and Hibernate Essentials: Learn Java ORM persistence

JPA & Hibernate: Master Database Mapping, Entity Relationships, CRUD Operations, and Spring Boot Integration

What you'll learn
Master JPA fundamentals and understand why it's the standard for Java enterprise database operations in Spring Boot and Jakarta EE apps
Learn object-relational mapping (ORM) concepts and how JPA simplifies database interactions compared to traditional JDBC approaches
Set up a complete JPA development environment with H2 database, configure persistence.xml, and establish database connections
Map Java classes to database tables using JPA annotations, handle various data types, and customize table/column properties
Implement and manage entity relationships (One-to-One, One-to-Many, Many-to-Many) with practical examples using Employee records
Master CRUD operations in JPA, including entity persistence, retrieval, updates, and deletion with proper transaction management
Understand entity lifecycles (Transient, Managed, Removed, Detached) and how the persistence context acts as a first-level cache
Write efficient JPQL queries, implement joins, and protect against SQL injection using parameterized queries
Create and customize join tables, implement cascading operations, and manage bidirectional relationships effectively
Build a Spring Boot application with JPA, configure database properties, and leverage Spring Data repositories
Implement declarative transaction management using @Transactional annotation and understand transaction propagation
Learn best practices for performance optimization including fetch types, lazy loading, and read-only transactions

Requirements
Intermediate-level Java programming experience
Basic understanding of object-oriented programming concepts
Familiarity with SQL and relational database basics
Basic knowledge of Maven for dependency management
Working knowledge of Spring Framework fundamentals (optional, but helpful)
Java Development Kit (JDK) 11 or higher installed
IDE (preferably IntelliJ IDEA or Eclipse)

Description
Master Java Persistence API (JPA) and Hibernate in this comprehensive course designed for Java developers seeking to excel in enterprise database operations. Through 53 detailed video lessons spanning over 8 hours of content, you'll progress from JPA fundamentals to advanced concepts, learning how to effectively map Java objects to database tables, manage complex entity relationships, and optimize database operations.Starting with the essentials, you'll learn why JPA has become the standard for Java enterprise development and how it simplifies database operations compared to traditional JDBC. The course takes a practical approach, guiding you through setting up a complete development environment with H2 database, configuring persistence.xml, and establishing database connections. You'll master critical concepts like object-relational mapping (ORM) while building a real-world application that demonstrates employee management systems.The curriculum deep dives into essential topics that often appear in technical interviews, including:- Implementation of One-to-One, One-to-Many, and Many-to-Many relationships with practical examples- Mastery of CRUD operations with proper transaction management- Advanced entity lifecycle management and persistence context optimization- Protection against SQL injection using parameterized JPQL queries- Integration with Spring Boot and leveraging Spring Data repositoriesYou'll learn industry best practices for performance optimization, including strategic use of fetch types, lazy loading, and read-only transactions. The course includes hands-on exercises and real-world scenarios that will help you understand common pitfalls and their solutions.The final sections focus on Spring Boot integration, teaching you how to leverage Spring Data JPA repositories and implement declarative transaction management. By the end of this course, you'll be confident in implementing database operations using JPA and Hibernate, understanding performance optimization techniques, and troubleshooting common issues.Whether you're preparing for technical interviews, working on enterprise applications, or transitioning to Java backend development, this course provides the comprehensive knowledge and practical skills needed to excel in Java persistence programming. Join thousands of developers who have mastered JPA and Hibernate through this structured, hands-on approach to learning.
