In this module, we’re going to look at one commonly used design for software: the Model-View-Controller, or MVC, Architecture. However, before we talk about designing software, let’s step back and talk about design in the real world.

The Design of Everyday Things

Think about the last time you went into a new building, spent a night in a hotel, or even just visited a bathroom in a trendy restaurant or museum.
