So what is a DDF or data flow diagram? A data-flow diagram is a way of representing a flow of data of a process or a system. The diagram also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow and there are no decision rules and no loops. The name itself indicates its focus is on the flow of information, where data comes from, where it goes and how it gets stored. Check out the following diagrams below.
Data flowcharts can be used to analyze an existing system or model a new one. The external entity included in the diagram is an outside system that sends or receives data, communicating with the system being diagrammed. They are typically drawn on the edges of the diagram. Meanwhile, the process includes any process that changes the data, producing an output. The data store consists of files or repositories that hold information for later use, such as a database table or a membership form.
The data flow includes the route that data takes between the external entities, processes and data stores. All of the diagrams are printable and you can find more of our educational diagrams in the other posts or categories! Download, print and get started!
