Java Persistence API (JPA) One-to-One Mapping Tutorial | JPA Explained

Java Persistence API – One-to-One Mapping Tutorial
In this tutorial, we’ll dive into the Java Persistence API (JPA) and learn how to implement One-to-One Mapping between entities. This is a fundamental concept in object-relational mapping (ORM) that allows you to link one entity directly to another, ensuring a clean and efficient database design.

🔹 What you’ll learn:
Introduction to JPA and One-to-One relationships
Using the @OneToOne annotation in entity classes
Configuring foreign keys and primary keys for mapping
Understanding mappedBy, cascade, and fetch options
Persisting and retrieving related entities with JPA

Best practices for designing One-to-One relationships in real-world applications

🎯 Who this video is for:
Java developers exploring persistence and ORM concepts
Students preparing for academic projects or interviews
Backend developers looking to strengthen their database integration skills

By the end of this video, you’ll be able to confidently design and implement One-to-One entity relationships in Java applications using JPA
