Hibernate is an ORM (Object-Relational Mapping) framework for Java that simplifies database interactions by mapping Java classes to database tables. It's widely used in enterprise applications for persistent data storage.

Key Features 🔧

  • Object-Relational Mapping: Automates conversion between Java objects and SQL database tables.
  • Session Management: Manages transactions and database connections via the Session interface.
  • Lazy Loading: Optimizes performance by loading data only when needed.
  • Caching: Supports second-level caching for improved efficiency.
  • Query Language: Provides HQL (Hibernate Query Language) for database queries.

Use Cases 🌐

  • Building scalable Java applications with relational databases
  • Simplifying complex database operations in enterprise systems
  • Integrating with Spring frameworks for seamless development

Getting Started 🚀

  1. Add Hibernate dependencies to your pom.xml or build.gradle.
  2. Configure hibernate.cfg.xml with database connection details.
  3. Annotate Java entities with @Entity and @Id.
  4. Use SessionFactory to create sessions and manage persistent objects.
