Artificial Coupling

Meaning 1

Alternative Terms

Definition

An artificial coupling is a coupling which is only there for technical reasons.

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
