Electronic data interchange (EDI) is a standard for the exchange of business data between systems. In the context of supply chain management, EDI can be used to exchange information such as orders, invoices, and shipping notices between systems.

Whether EDI data is real-time or not depends on the specific implementation and the systems being used. In some cases, EDI data may be exchanged in real-time, meaning that it is sent and received immediately as it becomes available. In other cases, EDI data may be exchanged on a scheduled basis, such as once per day or once per week.

In general, the use of EDI can help to improve the efficiency of supply chain operations by enabling the exchange of data between systems in a standardized and automated manner. However, the real-time nature of EDI data exchange will depend on the specific implementation and the needs of the business.
