Design elements - Data Flow Diagram (DFD)

The Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park provides three vector stencils libraries for drawing DFD using the ConceptDraw PRO diagramming and vector drawing software . The design elements library "Data flow diagram (DFD)" contains 15 symbols for drawing both context-level data flow diagram and Level 1 DFD. The design elements library "DFD, Gane-Sarson notation contains 12 symbols of Gane-Sarson DFD notation. The design elements library "DFD, Yourdon and Coad notation contains 22 symbols of Yourdon/ DeMarco DFD notation.
Use these DFD symbol libraries to design the process-oriented models, data-oriented models, data flowcharts, data process diagrams, structured analysis diagrams, and information flow diagrams.
"A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system, modeling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated. DFDs can also be used for the visualization of data processing (structured design).
A DFD shows what kinds of information will be input to and output from the system, where the data will come from and go to, and where the data will be stored. It does not show information about the timing of processes, or information about whether processes will operate in sequence or in parallel (which is shown on a flowchart)." [Data flow diagram.

The example "Design elements - Data Flow Diagram (DFD)" is included in the Data Flow Diagrams solution.

The vector stencils library "Business process BPMN 1.2 (Rapid Draw)" contains 12 symbols of objects, roles swimlanes, and task icons for creating the business process diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"BPMN models consist of simple diagrams constructed from a limited set of graphical elements. For both business users and developers, they simplify understanding business activities' flow and process. BPMN's four basic element categories are:
(1) Flow objects.
Events, activities, gateways.
(2) Connecting objects.
Sequence flow, message flow, association
(3) Swim lanes.
Pool, lane.
(4) Artifacts.
Data object, group, annotation.
These four categories enable creation of simple business process diagrams (BPDs). BPDs also permit making new types of flow object or artifact, to make the diagram more understandable. ...
Task.
A task represents a single unit of work that is not or cannot be broken down to a further level of business process detail without diagramming the steps in a procedure (which is not the purpose of BPMN)." [Business Process Model and Notation. Wikipedia]
