Data Synchronization is the process of collaborating with trading partners by sharing the same standardized catalogue information for use in their supply chain. Catalogue information includes location information (ship to locations, corporate headquarters etc.) as well as product information (Global Trade Item Number (GTIN), dimensions, descriptions, brand etc). In addition, data synchronization provides a framework to automatically communicate and update the information with all affected parties as changes are made. Data Synchronization enables Walmart to obtain all of the necessary product data it requires to trade with your company via electronic communication, through your GDSN-certified data pool.
