The viwes in Vortex keeps track of which fields and relations to load and show. Views are used and can be created in the GUI, but can also be a powerful tool to speed up data access in the API. When loading data through a view only one query is run to fetch data from the database.

Creating a view and selecting some fields to show

$view = new View();
$view->setTable( 'myTable' );
$view->addField( 'myField1' );
$view->addField( 'myField2' );
$view->addField( 'myRelation.relatedField1' );
