In this episode we go over what interfaces are and how to use them. We also discuss the concepts of dependency inversion, dependency injection and abstraction. Interfaces are an unbelievably powerful tool that allows you to use abstraction to create more robust and flexible code. It also gives you the ability to completely decouple your UI from the actual implementation of your business logic it retrieves data from. There are few tools as powerful as interfaces in an OOP developers toolset.
