to the same entity across different systems or
datasets. Here’s why:
Purpose of Global Identifier:
Unique Identification: Provides a unique identifier that can be used to recognize the same entity
across disparate systems and datasets.
Consistency: Ensures that different references or records pointing to the same entity are consistently
identified and managed.
Linking Equivalent Reference:
Equivalent Reference: Global identifiers link references that are equivalent, meaning they represent
the same real-world entity even if the data is stored differently in various systems.
Entity Resolution: Helps in resolving different records to a single entity, ensuring data consistency
and accuracy.
Example:
Customer Records: A customer might be listed in different systems (CRM, billing, support) with
slightly different details. A global identifier links these records to recognize them as the same
customer.
