Chaos is an independent, persistence-agnostic layer responsible for defining entities' business logic and relationships. It allows to describe a [Domain Model](https://en.wikipedia.org/wiki/Domain_model) without any assumption about the persistence layer.

> Note: The Chaos syntax is derived from [li3](http://li3.me/). If the syntax is not fully compatible with its predecessor, some effort has been made to keep the same clean and beautiful syntax.

Available datasources libraries:

- [chaos-database](https://github.com/crysalead/chaos-database): supports MySQL and PostgreSQL.

Chaos dramatically simplify the developpment of a datasources libraries by providing all persistence-agnostic logic like relationships, eager/lazy loading, validations, etc. at the root level. The only requirement is the datasource you envisionned to use need to be able to fetch a record/document thanks to a unique identifier (i.e no composite primary key).

Requirements
------------

[](#requirements)

- PHP 5.5+

Main Features
