Detailed Description

A unique identifier of an object within a database system, that is composed by a reference to the store it belongs to and the address of the object itself within the store.

It could happen that an object identifier is replicated by multiple stores, but the distinction is made by store: there cannot be two objects in the same store having the same identifier.
