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 🚀
- Add Hibernate dependencies to your
pom.xml
orbuild.gradle
. - Configure
hibernate.cfg.xml
with database connection details. - Annotate Java entities with
@Entity
and@Id
. - Use
SessionFactory
to create sessions and manage persistent objects.
