• Different people use different variations of the MVP pattern.
• Common and the most popular type of MVP pattern is by using a contract between the view and the presenter
• The contract is an interface between the view and the presenter
• The view calls a method to initiate an action in the presenter, the action can be to fetch the data from the model.
• Finally once the data is retrieved from the model the presenter notifies the view via the callback from the contract.
