Introduction to Hibernate and ORM

• Hibernate is an Object-Relational Mapping (ORM) framework for mapping Java objects to relational database tables.
• ORM is a technique for mapping objects in an object-oriented programming language to relational databases.

Why Use Hibernate?

• Open-source framework
• Provides a high-level API for common database operations
• Supports lazy loading, making it more efficient than other ORM frameworks
• Supports a wide range of database systems

How Hibernate Works

• Mapping between Java objects and database tables defined in Hibernate configuration file
• Hibernate framework uses configuration file to generate SQL queries
• Uses object-relational mapping (ORM) to map Java objects to database tables
• Allows developers to work with Java objects as if interacting directly with the database, without writing complex SQL queries

Hibernate Architecture

Conclusion

• Hibernate is a powerful ORM framework for building Java applications that interact with databases
• Provides a high-level API and supports a wide range of database systems
• Open-source license makes it a great option for developers.
