• Hibernate is No.1 Java Based Enterprise ORM Framework to Make Application Database Independent because of its ORM (Object Relational Mapping) implementation which makes Enterprise Applications easy to switch between database providers without chaning code as per their requirements.
• Reasons for Being No. 1
• Based on Design Patterns
• Easy Integration With Existing Application & Other Frameworks like Spring, Struts, J2EE etc
• Inbuilt Transaction Management
• Inbuilt Data Cache For Fast Data Retrieval
• Provides Data Persistence etc
• Easy to Learn & Implement.
• Pre-requisite - Core Java and SQL Basics.

📘 Course Name:

Hibernate Framework – Java ORM & Data Persistence

🎯 Course Objective:

To provide learners with a complete understanding of how Hibernate ORM works, enabling them to build data-driven Java applications with efficient persistence, CRUD operations, and database mappings using Hibernate and JPA (Java Persistence API).

• Java Developers (Beginner to Intermediate)
• Backend & Full-Stack Developers
• Software Engineers working with databases
• Computer Science students preparing for interviews
• Developers transitioning from JDBC to ORM

📝 Prerequisites:

• Basic knowledge of Core Java (OOP, Collections, Exceptions)
• Familiarity with JDBC and SQL
• Eclipse/IntelliJ IDE setup knowledge is helpful
