# ParrotDb

ParrotDb is an open source object database written in PHP.

Please note this is a fun project and not intended for use in production.

It is rather a proof of concept. However, feel free to check out the [benchmark section](https://github.com/Annoraaq/ParrotDb/wiki/Benchmarks)

 of the [wiki](https://github.com/Annoraaq/ParrotDb/wiki) to get a first impression of performance.

 

ParrotDb comes with an own [query language](https://github.com/Annoraaq/ParrotDb/wiki/Language-of-the-Birds) as well as an own [text file format](https://github.com/Annoraaq/ParrotDb/wiki/Feather-file-format).

# Installation

```git clone https://github.com/Annoraaq/ParrotDb.git```

```composer install```

# Run tests

```vendor/bin/phpunit```

# Basic usage

Let's say we have an example class:

```

class Bird

{

    public $id;

    public $name;

}

```

Now we need to create a session, a parser and a persistence manager:

```

$session = \ParrotDb\Core\PSessionFactory::createSession(

  "Testfile",

  \ParrotDb\Core\PSession::DB_XML

);

$parser = new \ParrotDb\Query\LotB\Parser\Parser($session->getDatabase());

$pm = $session->createPersistenceManager();

```

## Insert

```

$bird = new Bird();

$bird->id = 42;

$bird->name = "Pelecanidae";

$pm->persist($bird);

$pm->commit();

```

## Select

```

$constraint = $parser->parse('get Bird id = 42');

$resultSet = $pm->query($constraint);

$fetchedBird = $resultSet->first();

```

## Update

```

$constraint = $parser->parse('get Bird id = 42');

$resultSet = $pm->query($constraint);

$fetchedBird = $resultSet->first();

$fetchedBird->name = "Pidgeon";

$pm->commit();

```

## Delete

```

$constraint = $parser->parse('get Bird id = 42');

$pm->delete($constraint);

```
