Taxi Service Data Flow Diagram DFD Example

This sample shows the Data Flow Diagram of the Taxi Service and interactions between the Clients, Operators and Divers, as well as Orders and Reports databases.

Data Flow Diagram (DFD)

A Data Flow Diagram (DFD) illustrates the flow of data through an information system, visualizes how the information is handled in terms of inputs and outputs, how the data enter to system and leave it. It is effective to use a Data Flow Diagram for creation the system's overview, to show the system's scope and boundaries. There are two different types of notations for DFDs: Yourdon-Coad and Gane-Sarson, which differ in visual representations for processes, data flow, data stores, external entities, etc. Thus, for example the processes are depicted as circles in Yourdon-Coad notation and as rounded squares in Gane-Sarson notation. Gane-Sarson notation is usually used for visualization information systems and Yourdon-Coad - for system analysis and design. The Data Flow Diagrams solution included to Software Development area of ConceptDraw Solution Park offers a lot of DFD templates, samples and examples, libraries of vector stencils for construction without efforts the DFDs according to both Gane-Sarson and Yourdon-Coad notations.

Types of Flowchart - Overview

When designing a process or an instruction in clear and understandable way, you should consider creating a flowchart. You can avoid spending a lot of time understanding complex concepts as they get clear with different diagrams. The flowcharts are very popular diagram type, they are useful at different fields from the description business processes to the presentation of cooking recipes. Basic Flowchart, Business Process Modeling Diagram, Process Flowchart, Cross Functional Flowchart, Procedure Flowchart, Data Flow Diagram, IDEF Flowchart, SDL Diagram, Workflow Diagram, Document Flowchart, Program Flowchart, Value Stream Map, System Flowchart, Highlight Flowchart, Sales Flowchart are the main types flowchart. The ConceptDraw PRO is one of the professional applications which has great advantages and using which you can create different types of Flowcharts easy and fast. Try to draw an illustrative and comprehensible diagram in ConceptDraw PRO describing the processes instead of writing complex long text and make sure how it is convenient. Visio is expensive, and if you use it in a team environment, these costs are compounded. ConceptDraw PRO is an affordable alternative to Visio and luckily, it comes with a team plan. ConceptDraw PRO can import and export Visio files, so Mac users can collaborate with PC users stuck on Microsoft's software.

Business Process Modeling Resume

ConceptDraw PRO is a best business processes modeling software for graphical documenting processes of the company.

How To Create a Workflow Diagram

A workflow diagram is less general notation than a process flow diagram. Workflow as a term can apply to organizational process which involves people, resources, documents, sort of data, for instance; whereas a process is general collection of steps occuring in any sort of activity. That is why process flow diagram can be used as workflow diagram to describe business process, data flow or department interactions. The fastest way to create a workflow diagram is using pre-designed workflow template. ConceptDraw PRO with the Workflow Diagrams solution delivers rich set of workflow diagram templates you may start from.

Diagramming Software for UML Composite Structure Diagrams

UML Composite Structure Diagram shows the internal structure of a class and the possible interactions at this structure.

Process Flowchart

The main reason of using Process Flowchart or PFD is to show relations between major parts of the system. Process Flowcharts are used in process engineering and chemical industry where there is a requirement of depicting relationships between major components only and not include minor parts. Process Flowcharts for single unit or multiple units differ in their structure and implementation. ConceptDraw PRO is Professional business process mapping software for making Process flowcharts, Process flow diagram, Workflow diagram, flowcharts and technical illustrations for business documents and also comprehensive visio for mac application. Easier define and document basic work and data flows, financial, production and quality management processes to increase efficiency of your business with ConcepDraw PRO. Business process mapping software with Flowchart Maker ConceptDraw PRO includes extensive drawing tools, rich examples and templates, process flowchart symbols and shape libraries, smart connectors that allow you create the flowcharts of complex processes, process flow diagrams, procedures and information exchange. Process Flowchart Solution is project management workflow tools which is part ConceptDraw Project marketing project management software. Drawing charts, diagrams, and network layouts has long been the monopoly of Microsoft Visio, making Mac users to struggle when needing such visio alternative like visio for mac, it requires only to view features, make a minor edit to, or print a diagram or chart. Thankfully to MS Visio alternative like ConceptDraw PRO software, this is cross-platform charting and business process management tool, now visio alternative for making sort of visio diagram is not a problem anymore however many people still name it business process visio tools.

Model Based Systems Engineering

ConceptDraw PRO is a professional diagramming and vector drawing software. Now, enhanced with SysML Solution from the Software Development Area of ConceptDraw Solution Park, ConceptDraw PRO became an ideal software for model based systems engineering (MBSE).

IDEF3 Standard

Use Case Diagrams technology. IDEF3 Standard is intended for description and further analysis of technological processes of an enterprise. Using IDEF3 standard it is possible to examine and model scenarios of technological processes.

Workflow Diagram Data

Workflow Diagram created by using special software based on graphic mastering technology Arrows10. Its automatics follows the global concept of business graphics and diagramming. The practical effectiveness of Arrows10 technology used in ConceptDraw PRO are around the quick auto-arrows behaving as expected and connecting boxes of workflow diagram from workflow symbol to process flow symbol. ConceptDraw PRO is a workflow diagram software contains specific features help you to draw diagrams faster, such as RapidDraw, or Arrows10. There is also a rich set of samples and templates to give you an example of data may be visualized as workflow diagram.

ConceptDraw Arrows10 Technology

You can see that when you rotate a group, connectors change their angle, keeping their position inside of the grouped objects. If you decide to ungroup the objects, the connectors will adjust to keep lines parallel to the edges of the sheet. The magic of ConceptDraw Arrows10’s rotating group containing connectors, makes complex diagramming simple and easy. The way to connect objects has never been easier.

Basic Flowchart Symbols and Meaning

Flowcharts are the best for visually representation the business processes and the flow of a custom-order process through various departments within an organization. ConceptDraw PRO diagramming and vector drawing software extended with Flowcharts solution offers the full set of predesigned basic flowchart symbols which are gathered at two libraries: Flowchart and Flowcharts Rapid Draw. Among them are: process, terminator, decision, data, document, display, manual loop, and many other specific symbols. The meaning for each symbol offered by ConceptDraw gives the presentation about their proposed use in professional Flowcharts for business and technical processes, software algorithms, well-developed structures of web sites, Workflow diagrams, Process flow diagram and correlation in developing on-line instructional projects or business process system. Use of ready flow chart symbols in diagrams is incredibly useful - you need simply drag desired from the libraries to your document and arrange them in required order. There are a few serious alternatives to Visio for Mac, one of them is ConceptDraw PRO. It is one of the main contender with the most similar features and capabilities.

SysML Diagram

To draw SysML diagrams use the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.
