Back end
The parts of an application users do not see that handle data, rules and system interactions
What's it for?
Handles the hidden work behind an application, such as storing information and applying business rules.
For example…
When a booking confirms but the calendar never updates, the fault is usually in the back end.
A user clicks Buy; the back end checks stock, takes payment and records the order while the screen only shows the result
Think of it like…
The kitchen and pantry that make the restaurant meal possible
