How to Create a Data Flow Diagram

ConceptDraw Data Flow diagram (DFD) example
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 PRO allows you to draw a simple and clear Data Flow Diagram using special libraries.
The Data flow diagram (DFD) example "Payment for goods using UPS code scanner" shows data flow in process of payment for goods in the shop using the MaxiCode scanner.
"MaxiCode is a public domain, machine-readable symbol system originally created and used by United Parcel Service. Suitable for tracking and managing the shipment of packages, it resembles a barcode, but uses dots arranged in a hexagonal grid instead of bars. MaxiCode has been standardised under ISO/ IEC 16023.
A MaxiCode symbol (internally called "Bird's Eye", "Target", "dense code", or "UPS code") appears as a 1 inch square, with a bullseye in the middle, surrounded by a pattern of hexagonal dots. It can store about 93 characters of information, and up to 8 MaxiCode symbols can be chained together to convey more data. The centered symmetrical bullseye is useful in automatic symbol location regardless of orientation, and it allows MaxiCode symbols to be scanned even on a package traveling rapidly." [MaxiCode. Wikipedia]
This example of data flow diagram (Gane & Sarson notation) 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.

Database Flowchart Symbols

Database Flowchart Library, Here symbols to design data-base structure, use it to design data base models, or simple data-oriented models. The are special drawing tools for making data flowcharts, data process-oriented diagrams, analysis diagrams and information flow diagrams.
Data base diagrams describes inter-related data and tables. It describes roles and relationships, internal and external dependencies, data exchange conventions and structures of knowledge domain.
ConceptDraw Software provides number of data-base chart libraries including major 49 vector symbols. Use these DFD flowchart symbol libraries to design data-base structure and models, use it to design data base process-oriented models, or simple data-oriented models. The are special drawing tools for making data flowcharts, data process diagrams, structured analysis diagrams, and information flow diagrams.

Types of Flowcharts

Types of Flowcharts
A Flowchart is a graphically representation of the process, algorithm or the step-by-step solution of the problem. There are ten types of Flowcharts. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design the Flowchart of any of these types.

Process Flowchart, flowchart symbols, process flow diagram, flowchart maker
Flowchart is widely used in business, education and economic presentations to help the audience visualize the content better, or to find flaws in a process flow diagrams. Flowcharts are particularly useful for displaying how a process currently flow or could ideally function. Flowcharts can help you see whether the steps of a process are logical, uncover problems or miscommunications, define the boundaries of a process, and develop a common base of knowledge about a process.

ConceptDraw PRO flowchart software will help to quickly create new flowcharts, workflow, NS Diagram, BPMN Diagram, Cross-functional flowcharts, data flow diagrams and highlight flowcharts.

Feature-rich flowchart maker, free thousand flowchart examples and templates and colored symbols that will allow you to create professional looking flowcharts simply.

Accounting Information Systems Flowchart Symbols

What are Information Systems Flowchart Symbols
Accounting Information system is a combination of software and hardware, as well as organizational support. Information system - it is not only the software and computers with network equipment, but also a list of instructions and standards which can be notated using Accounting information systems flowchart symbols. All information systems can be divided into information retrieval and data processing systems. Data Flow model is a hierarchical model. Each process can be divided into structural components, that depict by corresponding flowchart symbols, showing the accounting information system in communication with the external environment. The major components of accounting information systems flowchart are: entities, processes, data stores, and data flows. The set of standard accounting information flowchart symbols is intended to show the relationships between the system components. ConceptDraw PRO can help to draw clear accounting information system diagrams using special flowchart symbols.
