Answer 1

Models : Models are where your main business logic should be handled and is a single instance of an object. The model will use the resource model to talk to the database and get/set data for it on save() and load().

Resource Model : A resource model is where your main C.R.U.D happens (Create, Read, Update and delete). The resource model shouldn’t contain business logic however it will talk to the adapters and basically talk to the database.
