An Ethernet data flow diagram depicts the flow of data through networks. Network-connected systems with functionality distributed across multiple nodes are common in digital systems. For example, data may flow from an order system to invoicing, payment, and logistics systems in an eCommerce store. The Ethernet data flow diagram is intended to represent data flows in an information system and data processing analysis during the structural projection. Data flow diagrams are frequently used in conjunction with human processes and can be represented as workflow diagrams. Another flowchart technique for designing data flow about organizational processes is the critical Process Flow Diagram. A necessary Process flow diagram may employ a different set of symbols than a traditional workflow diagram.
