The GS1 Global Data Synchronisation Network® (GDSN) enables trading partners to automatically share their business data with each other. This means organisations can have confidence that when one of their suppliers or retailers updates their database, their own database is similarly updated as a result. Everyone has access to the same continuously refreshed data.
For this to happen, each organisation needs to join a data pool certified and tested by GS1, who connect to the GS1 Global Registry®, a central directory which keeps track of connections, guarantees the uniqueness of data and ensures compliance with shared GS1 standards.
There are many data pools spread across the world.
