Example of DFD for Online Store (Data Flow Diagram) DFD Example

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.

Design Data Flow. DFD Library

Three DFD libraries, 49 vector shapes. Use these DFD symbol libraries to design the process-oriented models, data-oriented models, data flowcharts, data process diagrams, structured analysis diagrams, and information flow diagrams.

Examples Flowchart

ConceptDraw DIAGRAM diagramming and vector drawing software provides the unique Flowcharts Solution from the "Diagrams" Area of ConceptDraw Solution Park with variety of vector objects libraries and collection of examples Flowchart. Each example flowchart included in Flowcharts solution is a real help in drawing process, it can be the good base or perfect source of inspiration.

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.

Geo Map - Australia

The vector stencils library Australia contains contours of New Zealand and Australian states and mainland territories for ConceptDraw DIAGRAM diagramming and vector drawing software.

ConceptDraw DIAGRAM ER Diagram Tool

ER-diagram is a tool used for database modeling which allows to determine data and relationships among the data. These diagrams help to detail data storages and to document all the properties of designed system. ER-diagram contains entities, attributes of the entities and the relationships between them. Chen’s notation and Crow’s foot notation are commonly used to represent elements in ER-model. To create such diagram you should use specific software, such as Entity-Relationship Diagram solution for ConceptDraw DIAGRAM.
ConceptDraw ER Diagram Tool works across any platform, meaning you never have to worry about compatibility again. ConceptDraw DIAGRAM allows you to make Entity-Relationship Diagram (ERD) on PC or macOS operating systems.

ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw DIAGRAM.

Cloud Computing Architecture

The Cloud Computing Architecture is the structure of the system, which is based on the needs of end-user and includes the set of components and subcomponents required for cloud computing, among them cloud resources, services, middleware, software components, front-end platforms (cloud clients), cloud-based back end platforms (servers, storage), and a network (Internet, Intranet, Intercloud). When designing the Cloud Computing Architecture diagrams, the ConceptDraw DIAGRAM diagramming and vector drawing software advises to turn attention for the powerful Cloud Computing Diagrams solution from the extensive Computers and Network area of ConceptDraw Solution Park.
