There is an example of a data flow model, which shows a call center running the application called Edraw eCommunications. A data flow model is a diagrammatic description of how information flows and exchanges inside a system. Data flow models are used to depict the flow of data in an information system graphically by detailing the procedures involved in transporting data from input to file storage and report production. The company maintains the ERP database and the phone number database separately from the Edraw database. As you can see, all the customer information is stored in the Edraw Database. This example simplifies your creation of the data flow model and you can try to make one with EdrawMax.
