Hibernate Introduction

  • Hibernate is a robust, high-performance Object-Relational Mapping (ORM) framework for Java

  • It bridges the gap between object-oriented domain models and relational databases.

  • It provides a framework for mapping an object-oriented domain model to a traditional relational database,

  • Eliminating the need for repetitive, error-prone SQL and JDBC code.

Hibernate introduction

Why Hibernate?

  • Eliminates boilerplate JDBC code: Automates CRUD operations, reducing development time
  • Provides database independence: Write once, run on any database with minimal changes
  • Offers caching mechanisms: First-level and second-level caching improve performance
  • Supports lazy loading: Load data only when needed, optimizing memory usage
  • Handles transactions automatically: Manages transaction boundaries and concurrency
  • Object-oriented query language: HQL and Criteria API provide database-agnostic querying
