GUID (Globally Unique Identifier)


Definition:Globally Unique Identifier, a 32-character identifier unique across space and time. Frequently used to uniquely identify each instance of a data object (RefId), resulting in a mechanism for uniquely mapping a specific person, school, etc. in one application with the same entity in another application. (As defined by the SIF Association.)

What This Means: Whenever there is a need for a truly unique, unduplicated identifier, the GUID is used.
