## What it is
Doctrine ORM is an object-relational mapper for PHP 8.1+ that provides transparent persistence for PHP objects on top of the Doctrine DBAL database abstraction layer. It lets developers query databases using Doctrine Query Language (DQL), an object-oriented SQL dialect inspired by Hibernate's HQL.

## Use cases
- map PHP objects to database tables
- write database queries with an object-oriented query language
- manage entity relationships and associations in PHP
- persist and retrieve domain entities transparently
- build a Symfony or Laminas application with a mature ORM
- replace raw SQL with a query builder and DQL

## When to choose
- you are building a PHP application that needs robust, battle-tested object persistence
- you want rich association mapping, inheritance mapping, and event system support
- you prefer DQL/QueryBuilder over hand-written SQL
- you need a widely adopted ORM with extensive documentation and community support

## When to avoid
- you want a lightweight query builder without full entity management overhead
- your project uses PHP below 8.1
- you need extremely raw, hand-tuned SQL control for every query
- you are working outside the PHP ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: orm, database, database-driver, caching
- domain: databases, web-development, backend, developer-tools
- platform: php, cross-platform
- tags: doctrine, dql, query-builder, entity-mapping, persistence, dbal, symfony
