Foundations of Java Hibernate ORM and JPA

Writing raw SQL queries inside your Java applications can quickly become tedious, error-prone, and difficult to maintain. Hibernate ORM solves this by seamlessly mapping your Java objects to relational database tables, allowing you to focus on writing clean, maintainable code. This text-based course guides you from the absolute basics of Object-Relational Mapping (ORM) to managing complex database interactions. You will gain a solid conceptual foundation, learn how to configure Hibernate using modern Jakarta Persistence standards, and understand how to manage data persistence efficiently. What you'll learn: Understand the core concepts of Object-Relational Mapping and the database impedance mismatch; Configure Hibernate in modern Java applications using dependency management tools; Map Java classes to database tables using standard JPA annotations; Perform standard database operations such as inserting, updating, and deleting records; Manage entity relationships including one-to-many and many-to-many associations; Query databases using Java Persistence Query Language (JPQL). The course starts with essential terminology and architectural concepts before guiding you through configuration, entity mapping, and relationship management. You will learn through detailed written explanations, structured code snippets, and practical written exercises designed to test your understanding. This course is designed for beginner Java developers looking to transition from basic programming to database-driven applications, with no prior ORM experience required.
