title: Which relationship type to choose in Laravel Eloquent ORM on multiple relationships case
body: <p>I am new to Laravel and a bit confused about some definitions of ORM. 
  I am currently working on a simple Trouble ticket management system, and here is my question :
  (table: column, column,...) 
  tickets : id, description, equipment_id 
  equipments: id, name, vendor_id 
  vendor: id, name </p>
  
  <p>This is a very short resume of my tables and its relations, following Laravel's conventions. How can I build these models?</p>
  
  <p>Basically I need to retrieve, for example, how many tickets were opened to a certain vendor (how many times I called the vendor for support). </p>
  
  <p>Thank you in advance</p>
