LinkedIn – Java Persistence with JPA and Hibernate 2024-9

Java Persistence with JPA and Hibernate course. This course examines the incompatibility between object-oriented code and relational tables to understand the need for object-relational mapping (ORM). In this course, instructor Budhini Samarakodi covers the basics of JPA (Jakarta Persistence API) and shows you how to implement it in the popular ORM framework, Hibernate. Learn how to define an entity, map fields to columns, specify primary and composite keys, use annotations, map different types of entity relationships, perform basic CRUD operations, and more. Along the way, Budini offers insights into how to work with different types of queries and use a wide variety of constructs to accomplish key tasks. By the end of this course, you’ll also learn some of the best practices for applying the repository pattern to simplify and optimize your code. This course is integrated with GitHub Codespaces, an instant cloud development environment that provides all the functionality of your favorite IDE without requiring any local configuration. With GitHub Codespaces, you can get hands-on training from any device, at any time—while using the tools you’re likely to encounter at work. Check out the “Development Environment” video to get started.
