title: How to seed database in zend framework 3 (doctrine/migrations)?
body: <p>I'm creating migration like below. I couldn't find a way to seed db.
  Looking for something similar db:seed in laravel ? </p>
  
  <pre><code>public function up(Schema $schema)
  {
      $table = $schema-&gt;createTable('user_map');
      $table-&gt;addColumn('id', 'integer', ['autoincrement'=&gt;true]); 
      $table-&gt;addColumn('user_id', 'integer', ['notnull'=&gt;true]);
      $table-&gt;addColumn('relation_id', 'integer', ['notnull'=&gt;true]);
      $table-&gt;setPrimaryKey(['id']);
      $table-&gt;addOption('engine' , 'InnoDB');       
  }
  </code></pre>
