Event Sourcing
Raccoon is implemented using event-sourcing. This means that instead of storing only the current state, all changes are persisted. For example, creating an order is recorded as an event and so are all later edits, like setting a billing customer or creating and adding a shipment.

By adding a revert action for every event, undo and redo functionality can be implemented quite easily.
Analytics
