Communication between CRM and ERP for E-commerce scenario
Question more on lines of system architecture design.
We are planning to implement CRM E-commerce and wanted to find out more detail about the communication between CRM and ERP systems. Do they need to communicate in real time for this application, or is it mainly initial and delta loads? Is the amount of data exchanged huge ( necessitating both systems to be on the same network, or can they be on separate geographical locations )?
We also understand that E-commerce can also be done only using ERP. How does that differ from the CRM version?
