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 PRO 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.

Social Media Response DFD Flowcharts - diagramming software ( Mac PC )

Diagramming software for Mac and PC - create flowcharts and presentations for Social Media Organizing.

Internet Group Management Protocol (IGMP). Computer and Network Examples

The Internet Group Management Protocol (IGMP) is a communication protocol of the multicast transfer data in the IP networks. IGMP is used by routers and IP hosts for organizing the network devices in groups. This example was created in ConceptDraw PRO using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park. It shows the architecture of the network for delivering a multicast service using IGMP.

Types of Flowcharts

A Flowchart is a graphical representation of process, algorithm, workflow or step-by-step solution of the problem. It shows the steps as boxes of various kinds and connects them by arrows in a defined order depicting a flow. There are twelve main Flowchart types: Basic Flowchart, Business Process Modeling Diagram (BPMN), Cross Functional Flowchart, Data Flow Diagram (DFD), IDEF (Integrated DEFinition) Flowchart, Event-driven Process Chain (EPC) Diagram, Influence Diagram (ID), Swimlane Flowchart, Process Flow Diagram (PFD), Specification and Description Language (SDL) Diagram, Value Stream Mapping, Workflow Diagram. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design a Flowchart of any of these types. This solution offers a lot of special predesigned vector symbols for each of these widely used notations. They will make the drawing process of Flowcharts much easier than ever. Pay also attention for the included collection of ready Flowchart examples, samples and quick-start templates. This is business process improvement tools. If you are looking for MS Visio for your Mac, then you are out of luck, because it hasn't been released yet. However, you can use Visio alternatives that can successfully replace its functions. ConceptDraw PRO is an alternative to MS Visio for Mac that provides powerful features and intuitive user interface for the same.

ConceptDraw Arrows10 Technology

With ConceptDraw Arrows10 Technology - You can delete a single connector, by using the Delete key. If you need to delete more than a single connector in a complex diagram that contains many relations there is a special Delete Links tool which deletes the connectors only, no other drawing objects are deleted.

Examples of Flowchart

This sample shows the Flowchart of the ACC general account creation. This Flowchart describes the Start point, the process of the handling the user requests and the End point – creating of the account. The shapes represent the subprocesses and the arrows between the shapes shows the sequence of the actions. This sample was created in ConceptDraw PRO diagramming and vector drawing software using the Flowcharts solution from the "Diagrams" area of ConceptDraw Solution Park.
