Object Identification

Object identification in object models means that every object instance has a unique, unchanging identity. Object identification is often referred to as an OID. OIDs are used to reference object instances.

Characteristics of OIDs:

  • OIDs are independent of data contained in the object. The internal data values are not used to generate identification.
  • OIDs are generated by the object system. Users or programs have no control over identification.
  • OIDs last the lifetime of the object. The OID never changes even when the data contents may change.
