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. The Data Flow Diagrams solution from ConceptDraw Solution Park contains numerous predesigned DFD symbols for both notations, which help easy and effectively design professional-looking Data Flow Diagrams (DFDs) and DFD Process Diagrams.
"Data flow diagrams are one of the three essential perspectives of the structured-systems analysis and design method SSADM. The sponsor of a project and the end users will need to be briefed and consulted throughout all stages of a system's evolution. With a data flow diagram, users are able to visualize how the system will operate, what the system will accomplish, and how the system will be implemented. The old system's dataflow diagrams can be drawn up and compared with the new system's data flow diagrams to draw comparisons to implement a more efficient system. Data flow diagrams can be used to provide the end user with a physical idea of where the data they input ultimately has an effect upon the structure of the whole system from order to dispatch to report. How any system is developed can be determined through a data flow diagram model.
In the course of developing a set of levelled data flow diagrams the analyst/ designers is forced to address how the system may be decomposed into component sub-systems, and to identify the transaction data in the data model.
Data flow diagrams can be used in both Analysis and Design phase of the SDLC.
There are different notations to draw data flow diagrams (Yourdon & Coad and Gane & Sarson), defining different visual representations for processes, data stores, data flow, and external entities." [Data flow diagram. Wikipedia]
The DFD (Yourdon and Coad notation) example "Process of account receivable" 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.

Entity Relationship Diagram Examples

ConceptDraw PRO diagramming and vector drawing software offers the Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park. How many examples contains the Entity-Relationship Diagram (ERD) Solution! All Entity Relationship Diagram examples were designed and saved for ConceptDraw PRO users. Now they are available from ConceptDraw STORE.

Data structure diagram with ConceptDraw PRO

Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw PRO.

Cross-Functional Flowchart

Use of Cross-Functional Flowchart is a clear way of showing each team member’s responsibilities and how processes get shared or transferred between different responsible people, teams and departments. Use the best flowchart maker ConceptDraw PRO with a range of standardized cross-functional flowchart symbols to create the Cross-Functional Flowcharts simply and to visualize the relationship between a business process and the functional units responsible for that process. To draw the most quickly Cross-Functional Flowcharts, Cross Functional Process Maps, or Cross Functional Process Flow Diagrams, start with a Cross-functional flowchart samples and templates from ConceptDraw Solution Park. The ConceptDraw Arrows10 and RapidDraw technologies will be also useful for you in drawing. ConceptDraw PRO supports designing both types - horizontal and vertical Cross-functional flowcharts. A vertical layout makes the accents mainly on the functional units while a horizontal layout - on the process. If you need a Visio alternative in Mac OS X, try ConceptDraw PRO. Its interface is very intuitive and it’s actually much easier to use than Visio, yet somehow it’s just as powerful if not more so. ConceptDraw PRO performs professional quality work and seamless Visio interaction.
