Create your own Model Driven app - Dynamics 365 App

This is super confusing video, dont know even what he is trying to achieve.

@ovi.. great video , thanks for creating and sharing
, is there a way in which my model driven app , can auto populate the fields , if the customer exists in Dynamics 365 CRM .

So, i am in process of creating a model driven app and wanted the details of customer to be populated from CRM if it exists and if do not exits then user can create new customer in CRM .
Is such kind of integration possible in model driven app ? can you share any link of your video or doc link to show how this can be achieved .

many thanks
