title: Is there any best way to migrate existing tables without foreign keys to Laravel 5 with Eloquent?
body: <p>I am currently testing laravel 5.2 with MariaDB 10.0, and love this framework. I would like to migrate some part of existing web app (custom accounting web application) to Laravel 5.2. but there are some issues to migrate my current web application to Laravel.</p>
  
  <p><strong>(1) Current database doesn't use Foreign key</strong>
  As I read the Laravel manual, to use the Eloquent ORM( not Query builder), using Foreign key is mandatory as far as I understand. but existing database doesn't use Foreign key at all.</p>
  
  <p><strong>(2) Current Database structure doesn't fit to Laravel</strong>
  As I understand Laravel requrired their own styled table structure although they allow some overriding but not everything. but as I review my database, it needs a lot of modification to fit the laravel style.</p>
  
  <p>In summary, what I want to do is migrating some of existing tables and develope laravel web application using Eloquent, not Query builder.</p>
  
  <p>I am looking forward to your great opinions and advices.</p>
