Data Flow Diagrams are used to document the flow of data within a sales and inventory system. By analyzing the connectivity between different components and processes, such diagrams allow businesses to identify opportunities for streamlining their operations in order to optimize efficiency. The diagrams often contain symbols to represent data sources, such as databases or file stores, which indicate the starting point for each flow of information. Data flows are then depicted as arrows that show how information moves through the system, ultimately reaching its final destination. Use EdrawMax to download this template.
