# Data Flow Diagram Model

Example 2. DFD — Model of Small Traditional Production Enterprise

If you want to make any DFD, then everything you need to do is to download ConceptDraw DIAGRAM software as well as the needed solution from “ConceptDraw STORE” application or from this site. Thus, having “Data Flow Diagrams Solution” can simplify your work with drawing all the needed data flow diagrams and models within both notations, including the “Yourdon – de Marco”, as this notation can help to illustrate the data flow diagram objects, being interpreted in a way of processes transform the input data flows into the output ones and data depositories serve them only for keeping the “ingoing” data, without changing them.

The “Object Library” full of the design elements, that can be used in your drawings, can be found in the “Data Flow Diagram Solution” from ConceptDraw STORE application to help you to represent any data storage, objects, data flows, processes and data flow entities.

TEN RELATED HOW TO's:
When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology. There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.

Process mapping helps with sharing business results and reorganizing workflow. In almost every case, after creating a sales process flowchart the steps that are redundant become obvious for a manager. It's easy to find a flowchart examples that will help in developing one for your business. This sales process flowchart consists of a sequence of steps that represent a simple sale process. Each step is shown graphically by a rectangle representing processing steps or an activity, or a diamond representing a decision. These rectangles are linked by arrows, that indicate the direction of the sales workflow. ConceptDraw Sales Flowcharts solution delivers a the full set of classical flowchart notation symbols, along with sales-related icons and pictograms.

When studying a business process or system involving the transfer of data, it is common to use a Data Flow Diagram (DFD) to visualize how data are processed. Being initially used exclusively in regards to the flow of data through a computer system, now DFDs are employed as the business modeling tools. They are applied to describe the business events and interactions, or physical systems involving data storage and transfer. ConceptDraw DIAGRAM is a powerful Data Flow Diagram software thanks to the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.
