identifier

Related terms: tokens · symbols · identification number · ID

An internal or external reference key unique to each structure or other entity.

An identifier is a reference key used to identify entities and their associated data properties in a database or other data processing system.

The reference distinguishes an entity or its data within a particular system. It can come from an internal database or an external register.

An object name is a textual form of identification, while an identifier has its meaning within a reference system. A change in display name does not necessarily change the entity's reference key.
