## What it is
Hibernate ORM is the de facto object-relational mapping library for Java, implementing the Jakarta Persistence (JPA) specification to map domain models to relational databases. It provides idiomatic persistence with features like lazy loading, caching, auditing (Envers), and integrates with the wider Hibernate ecosystem including Search and Reactive.

## Use cases
- map Java objects to relational database tables
- implement JPA persistence in a Spring Boot application
- audit entity changes over time with Envers
- manage database transactions and lazy loading in Java
- replace boilerplate JDBC code with an ORM
- index entities into Elasticsearch or Lucene for full-text search
- persist domain models reactively with a non-blocking API

## When to choose
- building Java or JVM applications backed by relational databases
- you want JPA/Jakarta Persistence compliance with a mature, battle-tested implementation
- you need advanced ORM features like second-level caching, auditing, or schema tooling
- you want ecosystem integration with Hibernate Search, Validator, or Reactive

## When to avoid
- you need raw SQL performance control and prefer lightweight query builders like jOOQ
- working with non-relational databases (consider Hibernate OGM or a dedicated driver)
- building a microservice where a simple data mapper or plain JDBC suffices
- you are not on the JVM platform
