====== Natural Coupling ======
===== Meaning 1 =====

==== Alternative Terms ====
/*i.e. alternative names meaning the same thing*/


==== Definition ====
A **natural coupling** is a [[coupling]] between classes which represent concepts which are dependent in the same way.

==== Description ====

==== Examples ====

The following couplings are natural ones:
  * ''Library'' depending on ''Book''
  * ''Stopwatch'' depending on ''Time''
  * ''Order'' depending on ''OrderItem''
  * ''OrderProxy'' depending on ''Order''
  * ...

The following couplings are artificial:
  * ''Time'' depending on ''Stopwatch'' (time should be meaningful without a stopwatch)
  * ''OrderItem'' depending on ''Order'' (an order item way at least be viewed separately from the order whereas an order without any items is not an order anymore)
  * ''Order'' depending on ''DatabaseConnection'' (an order which is not persisted is normally still an order, the dependency is not necessary from a conceptual point of view)
  * ''Order'' depending on ''OrderProxy''
  * ...

==== Alternative Definitions ====
