Learn Hibernate and JPA

Master persistence with the Java specification and Hibernate implementation

Learn Java Persistence with JPA/Hibernate

Using an ORM (Object-Relational Mapping) is a standard and naturally very useful approach to persistence. Simply put, it’s buidling an abstraction layer between your domain and the database. This allows us to interact with the database through an OO paradigm.

The JPA specification defines the standard for ORM in Java. And, of course, it’s most often paired in practice with its most popular implementation – Hibernate.

In this course, we’ll start from scratch and get a practical understanding of the two tools and how they’re connected.

Then, we’ll learn how to map our domain, implement CRUD operations, define constraints, relationships, inheritance, handle different data types. Finally, we’ll dive into more advanced features like transactions, caching, and lazy loading.

Actual coding practice through a fully operational project – definitely the best way to learn persistence with JPA/Hibernate

The essential guide for getting started with JPA and Hibernate. The 4 modules cover the initial setup and how to define Java objects as managed entities.

In addition to the basics, you’ll also learn how to map relationships between entities, different data types, strategies for handling auto-generated IDs, how to perform operations on the data, and more.

Everything you need to create a basic persistence layer.
