Database schema visualization

Project goal

The aim of this project is to generate database documentation from sql schema.

Supported databases

• MySQL
• MariaDB
• Apache Cassandra (Basics)

Supported Output formats

• PNG, SVG image
• Plantuml raw text
• Json

Pre Installation

• https://graphviz.gitlab.io/download/

Installation

$ composer require pongee/database-schema-visualization
or add it the your composer.json and make a composer update pongee/database-schema-visualization.

Usage

In console

PNG export

$  php ./database-schema-visualization mysql:image ./example/schema/sakila.sql > ./example/img/sakila.png
$  php ./database-schema-visualization mysql:image --type png ./example/schema/sakila.sql > ./example/img/sakila.png

Output:

SVG export

$  php ./database-schema-visualization mysql:image --type svg ./example/schema/sakila.sql > ./example/img/sakila.svg

Json export

$  php ./database-schema-visualization mysql:json ./example/schema/sakila.sql

Plantuml export

$  php ./database-schema-visualization mysql:plantuml ./example/schema/sakila.sql

PHP

Png export

<?php declare(strict_types=1);

use Pongee\DatabaseSchemaVisualization\DataObject\Sql\Database\Connection\ConnectionCollection;
use Pongee\DatabaseSchemaVisualization\Export\Plantuml;
use Pongee\DatabaseSchemaVisualization\Generator\ImageGenerator;
use Pongee\DatabaseSchemaVisualization\Parser\MysqlParser;

include __DIR__ . '/../../vendor/autoload.php';

$sqlSchema = '
  CREATE TABLE IF NOT EXISTS `foo` (
    `id` INT(10) UNSIGNED NOT NULL COMMENT "The id"
   ) ENGINE=innodb DEFAULT CHARSET=utf8;
';

$sqlParser                = new MysqlParser();
// $cqlParser                = new \Pongee\DatabaseSchemaVisualization\Parser\CassandraParser();
$plantumlExport             = new Plantuml(file_get_contents(__DIR__ . '/../../src/Template/Plantuml/v1.twig'));
$forcedConnectionCollection = new ConnectionCollection();
$imageGenerator             = new ImageGenerator(
    'png',
    __DIR__ . '/../../bin/plantuml.jar',
    __DIR__ . '/../../tmp/'
);

$schema = $sqlParser->run($sqlSchema, $forcedConnectionCollection);

print $imageGenerator->generate($plantumlExport->export($schema));

Json export

<?php declare(strict_types=1);

use Pongee\DatabaseSchemaVisualization\DataObject\Sql\Database\Connection\ConnectionCollection;
use Pongee\DatabaseSchemaVisualization\Export\Json;
use Pongee\DatabaseSchemaVisualization\Parser\MysqlParser;

include './vendor/autoload.php';

$sqlSchema = '
  CREATE TABLE IF NOT EXISTS `foo` (
    `id` INT(10) UNSIGNED NOT NULL COMMENT "The id"
   ) ENGINE=innodb DEFAULT CHARSET=utf8;
';

$mysqlParser                = new MysqlParser();
$jsonExport                 = new Json();
$forcedConnectionCollection = new ConnectionCollection();

$schema = $mysqlParser->run($sqlSchema, $forcedConnectionCollection);

print $jsonExport->export($schema);

This will generate:

    "tables": {
        "foo": {
            "columns": [
                {

                    "comment": "The id"
                }
            ],
