A customer data flow is a path to move from one part of the information system to another. A customer data-flow diagram example represents a single data element such as the customer ID, or it can represent a set of data elements or a data structure. The visual representation between a customer and how he requests an order makes a good communication tool to access and understand the system. As shown in the image, a customer can submit the request for the order, and the details will be sent across to the payment department and warehouse. Once all the information is received and correctly accessed, then the order will be shipped to the customer. The customer's data flow diagram can be designed using EdrawMax or EdrawMax Online as it has highly customizable tools that let you create eye-catching data flow diagrams.
