Data Flow Diagram Model

Data Flow Diagram (DFD) is a technique of graphical structural analysis, describing the sources external to the system, recipients of data, also logical functions, data flows and data stores that are accessed. The DFD's goal is to show how each process converts its inputs into the outputs and to identify relationships between these processes, at this make the system's description clear and understandable at every level of detail. Historically happened that for describing Data Flow Diagrams are used two notations - Yourdon and Gane-Sarson that differ each from other by graphical representation of symbols. The DFD model, like most other structural models is a hierarchical model. Each process can be subjected to decomposition on the structural components, the relationships between which in the same notation can be shown on a separate diagram. Typically, several DFD models are built when modeling the system. ConceptDraw DIAGRAM software enhanced with Data Flow Diagrams solution ideally suits for creation DFD models and professional drawing Data Flow Diagrams.

Data Flow Diagram Examples

Data flow diagrams (DFDs) are effective to reveal relationships among the various components in a program or system. This type of diagrams is an important and useful technique for modeling an information system, its process aspects, for showing a system as a single high-level process. DFD lets illustrate the flow of data, how the input data are transformed to output results across the sequence of functional transformations. DFD consists of four major components: entities, processes, data stores, data flows.

Data Flow Diagrams

The information system manages the flow of data introduced into the system. To graphically represent and document the flow of data through some information system is used a Data Flow Diagram (DFD). DFD is a way to visualize the flow of data or data processing, to clearly demonstrate what type of data or information is transferred, where they come from and where are sent. It lets to create an overview of the system, to depict the major steps, and effectively model the processes. DFDs are helpful for analyzing and modifying the business systems. Traditionally are used two notations for DFDs creation - Yourdon-Coad and Gane-Sarson. ConceptDraw DIAGRAM software offers a special Data Flow Diagrams solution from Software Development area, which enables to quickly and simply create professional Data Flow Diagrams including the data storage, data flows, external entities, functional transforms, control transforms and signals.

Data Flow Diagram

Data Flow Diagram (DFD) is the part of the Structured Systems Analysis and Design Methodology (SSADM), which is intended for information systems projection and analysis. Data Flow Diagrams allow graphically represent the data flows in information system and analyze the data processing during the structural projection. This type of diagrams lets visually show a work of information system and results of this work, it is often used in connection with human processes and can be displayed as Workflow diagram. Data Flow Diagram visualizes processes and functions, external entities, data depositories, and data flows connecting these elements and indicating direction and data character. Each of these elements used for DFD has its own graphical notation. There are two notations to draw DFDs - Yourdon & Coad and Gane & Sarson. ConceptDraw DIAGRAM extended with Data Flow Diagrams (DFD) solution from Software Developmant area is ideal for designing professional looking DFDs, which can be then easily exported in various formats.

Software and Database Design with ConceptDraw DIAGRAM

Unified Modeling Language (abbr. UML) is a modeling language used by software developers and software engineers for developing diagrams, expressive modeling, visualization, construction, specification, and documentation an information about software-intensive systems. There are used many types of UML diagrams, joined in main groups, each of them has its own functional abilities and applications: Behaviour diagrams illustrate the functionality of software systems, Structuring diagrams depict a structure of objects at the systems, Interaction diagrams show the flow of control and data among the things in a modeling system. UML has a lot of practical applications in varied areas, among them software development, hardware design, banking and financial services, telecommunication, science, research, enterprise information system, distributed Web-based services, user interfaces for web applications, medical electronics, patient healthcare systems, etc. ConceptDraw DIAGRAM extended with Rapid UML solution is a perfect tool for UML diagramming.

Data Flow Diagram Process

Data Flow Diagram (DFD) is a hierarchy of functional processes, connected by data flows. The purpose of this presentation is to show how each process converts its inputs into outputs and to identify relationships between these processes. DFD is convenient way of modeling and construction the information processes, it step-by-step illustrates the flow of information in a process. For construction a DFD traditionally are used two different notations, which appropriate to the methods of Yourdon-Coad and Gane-Sarson. These notations slightly different from each other by graphical representation of symbols for processes, data stores, data flow, external entities. When designing a DFD it is required to decompose the system into the components (sub-systems), for explaining a complex system you may need represent numerous levels.

Example of DFD for Online Store (Data Flow Diagram)

Data Flow Diagram (DFD) is a methodology of graphical structural analysis and information systems design, which describes the sources external in respect to the system, recipients of data, logical functions, data flows and data stores that are accessed. DFDs allow to identify relationships between various system's components and are effectively used in business analysis and information systems analysis. They are useful for system’s high-level details modeling, to show how the input data are transformed to output results via the sequence of functional transformations.
