## What it is
Cycle ORM is a PHP DataMapper ORM and data modelling engine with a powerful query builder and dynamic mapping schema. It is designed to work safely in both classic and long-running (daemonized) PHP applications such as RoadRunner.

## Use cases
- map PHP objects to database tables in a PHP application
- build type-safe database queries with a query builder
- model has-one, has-many, many-to-many and polymorphic relations
- run an ORM inside long-running PHP workers like RoadRunner
- manage database schema, migrations and introspection
- implement repositories and unit-of-work persistence patterns
- support multiple databases like MySQL, Postgres, SQLServer and SQLite

## When to choose
- you need a DataMapper-style ORM in PHP with plain old PHP objects
- your app runs in long-lived processes and needs an immutable, disposable-UoW ORM core
- you want flexible schema definition with or without annotations/attributes and code generation
- you need polymorphic relations, single table inheritance, or cyclic graph persistence
- you use the Spiral framework or RoadRunner stack

## When to avoid
- you prefer Laravel Eloquent's Active Record style and tight Laravel integration
- you need a mature ecosystem with as many third-party extensions as Doctrine
- your project is a small script where a lightweight query builder or raw PDO suffices
- you rely on DBMS-specific features beyond Cycle's unified DBAL abstraction
