How do you split "fat" models?

Question

Ok, so I moved away from fat controllers. That's actually better. But now I have a fat model that I would like to split for better readability and easier maintenance. What is the recommended route ?

example from a current script :
1. initiate $ctrl
2. initiate $dbmodel

$ctrl->parser class , parsing data (using $element objects). All db calls are made to global $dbmodel
$ctrl->matchmaker class, matching content with targets. All db calls are made idem
$ctrl->mailer class, idem.

The $dbmodel is now way bigger than I like. Is there a proper/recommended way to split

Read it multiple times before, it doesn't indicate ways to actually organize the model — Malaiac, Feb 10 '18 at 22:51

Perhaps read up on clean architecture?

Specifically, one could create a service layer that is wrapped on your model layer.

The service layer will mutate the entities and have your domain business logic in that layer, or non-domain business logic.

That is the best I can answer your poorly written question.
