#5 Hibernate One-to-Many & Many-to-One Mapping with HQL Tutorial | Learn with Examples

Welcome to this comprehensive tutorial on Hibernate, focusing on One-to-Many and Many-to-One mappings and an introduction to Hibernate Query Language (HQL) with practical examples!

In this video, we dive deep into some of the most crucial concepts when working with Hibernate in Java applications. If you're new to Hibernate or want to improve your understanding of how data relationships are handled in ORM (Object-Relational Mapping), this video is for you.

What You Will Learn:
One-to-Many Mapping: We'll begin by exploring the One-to-Many relationship in Hibernate, a scenario where one entity is related to multiple other entities. This type of relationship is commonly used in database design, such as when a customer has many orders or an author writes many books. You'll learn how to properly map these relationships in Hibernate using annotations, and see a real-world example of how it works.

Many-to-One Mapping: Following the One-to-Many, we discuss the Many-to-One mapping. This relationship is the inverse of One-to-Many, where multiple instances of an entity are related to a single instance of another entity. Understanding the Many-to-One mapping is crucial for navigating complex database relationships, and in this tutorial, you'll learn how to implement it efficiently.

Hibernate Query Language (HQL) Introduction: HQL is an object-oriented query language, similar to SQL but tailored for Hibernate. It allows you to interact with your database in an object-oriented way, instead of dealing with raw SQL queries. We'll walk you through an intro to HQL, its syntax, and some basic queries to get you started with querying your mapped entities in a cleaner, more efficient manner.

Practical Examples: Throughout the video, we provide practical examples of how to implement One-to-Many and Many-to-One mappings and query your data using HQL. You’ll learn how to perform CRUD operations (Create, Read, Update, Delete) and see how these mappings can help simplify your application's interactions with the database.
