# ORM

[![Build Status](https://github.com/formal-php/orm/workflows/CI/badge.svg?branch=master)](https://github.com/formal-php/orm/actions?query=workflow%3ACI)

[![Type Coverage](https://shepherd.dev/github/formal-php/orm/coverage.svg)](https://shepherd.dev/github/formal-php/orm)

This ORM[^1] focuses to simplify data manipulation.

This is achieved by:

- using immutable objects

- each aggregate _owning_ the objects it references

- using monads to fetch aggregates (from the [Innmind](https://github.com/Innmind) ecosystem)

- using the specification pattern to match aggregates

This allows:

- simpler app design (as it can be [pure](https://innmind.github.io/documentation/philosophy/oop-fp/#purity))

- memory efficiency (the ORM doesn't keep objects in memory)

- long living processes (since there is no memory leaks)

- to work asynchronously

## Installation

```sh

composer require formal/orm

```

## Usage

```php

use Formal\ORM\{

    Manager,

    Sort,

};

use Formal\AccessLayer\Connection\PDO;

use Innmind\Url\Url;

$manager = Manager::sql(

    PDO::of(Url::of('mysql://user:pwd@host:3306/database?charset=utf8mb4')),

);

$_ = $manager

    ->repository(YourAggregate::class)

    ->all()

    ->sort('someProperty', Sort::asc)

    ->drop(150)

    ->take(50)

    ->foreach(static fn($aggregate) => doStuff($aggregate));

```

This simple example will retrieve from the database `50` elements (from index `151` to `200`) sorted by `someProperty` in ascending order and will call the function `doStuff` on each aggregate.

> [!NOTE]

> The elements are streamed meaning only one aggregate is in memory at a time allowing you to deal with long lists of elements in a memory safe way.
