Frameworks and business rules

Don’t let framework components into your core code.

Define boundaries between core and infrastructure components to enable a pluggable system.¹

Frameworks are not built but extracted — David Heinemeier Hansson

The framework’s architecture exists to support the tool rather than any business.
