Example of DFD for Online Store (Data Flow Diagram)

Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are 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.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method SSADM is the method which is used at projecting and analysis of information systems. SSADM is based on the data flow diagrams. At the description of data flows out of the system and into the system DFD, which denote boundaries of the system, are used.

UML Use Case Diagram Example. Registration System

The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development. This diagram consists of actors, use cases and relationships between them. When constructing a diagram, common notation elements can also be used: notes and extension mechanisms.

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the types of user’s interactions with the system and is used at the registration and working with the database system.

DFD Flowchart Symbols

A Data Flow Diagram (DFD) is a graphical technique which allows effectively model and analyze the information processes and systems. The ability to fast and easy create the DFDs is made possible with Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park. For designing the Data Flow Diagrams are used simple DFD flowchart symbols which are connected each other by arrows depicting the data flow from one step to another.

Components of ER Diagram

ConceptDraw gives the ability to draw ER diagram (ERD) for visual describing database using the entity relationship symbols, work flow shapes, entity relationship stencils. Entity-Relationship model making possibility to describe a database using the components of ER Diagram in which in the tables data can be the point to data in other tables - for instance, your entry in the database could point to several entries.

UML Diagram for System

This sample shows the UML Class Diagram of delivery system. On this diagram you can see the classes that are connected with aggregation and composition associations indicated with the multiplicity. This sample can be used by delivery services, postal services.

Stakeholder Management System

Stakeholder management is a critical component to the successful delivery of any project, programme or activity.
ConceptDraw DIAGRAM is a powerful diagramming and vector drawing software. Now, thanks to the Stakeholder Onion Diagrams Solution included to the Management Area of ConceptDraw Solution Park, ConceptDraw DIAGRAM became also unique stakeholder management system design software.

ConceptDraw DIAGRAM DFD Software

Our DFD software ConceptDraw DIAGRAM allows you to quickly create DFD with data storages, external entities, functional transforms, data flows, as well as control transforms and signals. DFD program ConceptDraw DIAGRAM has hundreds of templates, and a wide range of libraries with all nesassary ready-made drag-and-drop.

Data Flow Diagram Symbols. DFD Library

Data Flow Diagrams show information transfers and process steps of a system. The general concept is an approach of a depicting how occurs input in a system, further processes and what runs out. The aim of DFD is in accomplishing of understanding between developers and users. Data flow diagrams are maintained with other methods of structured systems analysis.

Data Flow Diagram Model

The DFD (Yourdon and Coad notation) example "Model of small traditional production enterprise" below was created using the ConceptDraw DIAGRAM diagramming and vector drawing software extended with the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.
