Logical Data Modeling - Global Identifier (Fully Qualified Name, Canonical Form)


A global identifier identify uniquely a primary element (entity or relationship) in the global scope

It's also generally known as:

  • the fully qualified id
  • the fully qualified name
  • the canonical form (global unique id)



A fully qualified identifier is composed of:

<MATH> \Large GlobalIdentity = NameSpace + PrimaryKey </MATH>


The identifier describes the identity of an entity.

If there is no namespace functionality in the system, you will get this formula <MATH> \Large id+entity = identity </MATH>
