Editing Identity (object-oriented programming) (section)

== Identity and object-oriented conceptual model ==
Identity allows the construction of a platonic ideal world, the [[ontology (information science)|ontology]] or conceptual model,  that is often used as basis of object-oriented thinking. The conceptual model describes the [[client (computing)|client]] side view to a [[application domain|domain]], terminology or an [[application programming interface|API]]. This world contains point-like objects as [[instance (computer science)|instances]], properties of the objects and links between those objects. The objects in the world can be grouped to form [[class (computer science)|class]]es. The properties of the objects can be grouped to form [[role (object-oriented programming)|role]]s. The links can be grouped to form [[association (object-oriented programming)|association]]s. All locations in the world together with the links between the locations form the structure of the world. These groups are [[datatype|type]]s of the corresponding instances of the world.
