Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams graphically represent the information transfers and process steps of a system. They visually depict how data are processed by a system in terms of inputs and outputs, how occurs the input in a system, how the data flow through an information system and where they are stored, and how occurs output from the system. DFDs give the overview of the system and models the processes aspects, they are maintained with other methods of structured systems analysis. The main goal of DFDs is achievement of understanding between developers and users. For their construction are used two notations - Gane-Sarson and Yourdon, each of them uses its own set of symbols. Data Flow Diagrams solution from Software Development area extends the ConceptDraw DIAGRAM software with templates, samples, and predesigned libraries of data flow diagram symbols for both notations, allowing you easy design the process-oriented and data-oriented models, draw the Data Flow Diagrams, Data Flowcharts, Data Process Diagrams, Information Flow Diagrams, Structured Analysis Diagrams, etc.

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.

UML Diagram of Parking

This sample shows the Use Case Diagram of parking lot control system. On this sample you can see use cases represented as ovals and three actors represented as figures of persons that employ these use cases. Associations between actors and use cases are shown as lines. UML Diagram of Parking - This diagram can be used for understanding the process of working the car parking, at the projection and construction the parking by building companies and for automation the existing parkings.

Developing Entity Relationship Diagrams

When you need to visually represent the structure of relational database, Entity relationship diagram (ERD) is a type of diagram for that case. Most entity-relationship diagrams can be built with objects from Flowchart solution or ERD Solution which contains inbuilt templates. Follow these steps to create your own custom ERD diagram. Don't be frightened if it looks complex, ConceptDraw DIAGRAM makes it easy to create an ERD, and hundreds of other diagrams, in minutes.

DFD Library System

The Data Flow Diagram (DFD) is a graphical technique used for effective modeling and analyzing the information processes and systems. Having at the disposal the DFD library system and newest powerful tools of ConceptDraw DIAGRAM diagramming and vector drawing software supplied with Data Flow Diagrams (DFD) solution from the Software Development area of ConceptDraw Solution Park, you can design fast and easy the Data flow diagrams, Data flowcharts, Data flow models, Data flow process diagrams, Process-oriented models, Data-oriented models, Data process diagrams, Structured analysis diagrams, Information flow diagrams of any type and complexity. For designing the Data Flow Diagrams in ConceptDraw DIAGRAM software are used the simple DFD flowchart symbols from the offered DFD libraries - Data Flow Diagram (DFD) library, Yourdon and Coad Notation library, and Gane-Sarson Notation library. The DFD objects are need to be connected each other by the arrows to depict the data flow from one step to another, that you can do in seconds in ConceptDraw DIAGRAM , as well as set desired design of your diagram.
