+Doctrine provides easy taversal of your database.  Consider the following imaginary query:
+```php
+$entity->getRelation()->getField1()
+                      ->getField2()
+                      ->getManyToOne()->getName()

+       ->getOtherRelation()->getField4()
+                           ->getField5()
+```

+{ entity { relation { field1 field2 manyToOne { name field 3} } otherRelation { field4 field5 } } }
