MVC design patterns
Model-View-Controller (MVC) is a design
pattern that simplifies application
development and maintenance.
1. Model: Responsible for the business logic of an
application
2. View: Typically what would be considered web
design, or templating.
3. Controller: The controller layer glues everything
together.

• “We need to open up our apps/data to the
outside, safely, and visually appealing
