Data Flow Diagrams (DFD)

Data Flow Diagrams solution extends ConceptDraw DIAGRAM software with templates, samples and libraries of vector stencils for drawing the data flow diagrams (DFD).

Data Flow Diagrams (DFD)

This DFD sample was created on the base of the figure illustrating "A Survey of Object-Oriented Methods" by Peter Biggs from University of Durham.

"Object-oriented analysis and design (OOAD) is a popular technical approach to analyzing, designing an application, system, or business by applying the object-oriented paradigm and visual modeling throughout the development life cycles to foster better stakeholder communication and product quality.
According to the popular guide Unified Process, OOAD in modern software engineering is best conducted in an iterative and incremental way. Iteration by iteration, the outputs of OOAD activities, analysis models for OOA and design models for OOD respectively, will be refined and evolve continuously driven by key factors like risks and business values." [Object-oriented analysis and design. Wikipedia]
The DFD example "Coad/ Yourdon's Object-Oriented Analysis model" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.

How to Create a Data Flow Diagram

Data flow diagramming is a highly effective technique for showing the flow of information through a system. Data flow diagrams reveal relationships among and between the various components in a program or system. DFD is an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations. The set of standard symbols is used to depict how these components interact in a system. ConceptDraw DIAGRAM allows you to draw a simple and clear Data Flow Diagram using special libraries.

Software Development Area

Solutions from the Software Development Area of ConceptDraw Solution Park collect templates, samples and libraries of vector stencils for drawing the software engineering diagrams and user interface design prototypes.

Telecommunication Network Diagrams

Telecommunication Network Diagrams solution extends ConceptDraw DIAGRAM software with samples, templates, and great collection of vector stencils to help the specialists in a field of networks and telecommunications, as well as other users to create Computer systems networking and Telecommunication network diagrams for various fields, to organize the work of call centers, to design the GPRS networks and GPS navigational systems, mobile, satellite and hybrid communication networks, to construct the mobile TV networks and wireless broadband networks.

Software development with ConceptDraw DIAGRAM

ConceptDraw possesses powerful tools for designing of technical documentation for object-oriented projects. The libraries included in the package allow to easily draw class hierarchies, object hierarchies and diagrams of data flows with the use of the most popular notations, including UML and Booch notations.
