Design Element: Crows Foot for Entity Relationship Diagram - ERD

Creating an ERD requires choosing a specific set of notations that best serve the specific database being designed. ConceptDraw PRO software extended with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park allows you to draw ER diagrams for depicting a database using the ERD diagram design element Crow's Foot - Crow′s Foot notation icons.

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.

Entity Relationship Diagram Symbols

Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.
ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw PRO.

Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for data modeling, system design and illustrating the logical structure of databases.
Professional ERD drawing is an essential software engineering method for database modeling. ConceptDraw PRO as a powerful Entity Relationship Diagram Software Engineering offers the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park.

UML Class Diagram Generalization Example UML Diagrams

This sample was created in ConceptDraw PRO diagramming and vector drawing software using the UML Class Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample describes the use of the classes, the generalization associations between them, the multiplicity of associations and constraints. Provided UML diagram is one of the examples set that are part of Rapid UML solution.

JSD - Jackson system development

Jackson System Development (JSD) is a linear method of system development created by Michael A. Jackson and John Cameron in the 1980s. It comprises the whole software life cycle directly or providing a framework for more specialized techniques.
When implementing the Jackson System Development method and designing JSD diagrams, you can succesfully use the powerful and helpful tools of ConceptDraw PRO software extended with Entity-Relationship Diagram (ERD) solution from the Software Development area of ConceptDraw Solution Park.

Campus Area Networks (CAN). Computer and Network Examples

A campus network provides wireless access to the Internet or LAN to users located in two or more buildings or in the open space surrounding those buildings. A campus network is usually set in the campus of a university, but the same kind of planning and design can be applied for other purposes. For example, the campus network can used for an office or industrial park, in a public place like a supermarket with an entertainment center, even on a farm. Another form of temporary campus network can exist during special events such as music festivals or rallies.
The elementary campus networks arise spontaneously: the radio signals from the access points, which provide network inside the building are not limited to its walls, so any user in the backyard can also get wireless network access. The larger and more complex campus network may have additional access points in places specially chosen for serving clients, i.e., on the lawn in front of the college or in a coffee shop around the corner.
