A set of software design principles and patterns that enable us to develop loosely coupled code.
Why the loose coupling of code
A couple of benefits from loosely coupled code is
- easy to extend,
- easy to test
- easy to maintain.

- View contains the UI elements of our application
- Presentation is our UI logic
- Data access interacts with our data store
- Data store is where our actual data resides
