Entity-Relationship Diagram (ERD)

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.

ConceptDraw DIAGRAM Network Diagram Tool

With ConceptDraw DIAGRAM you can diagram a network or create a computer network diagram using specialized libraries of network components such as computers, hubs, smart connectors etc. that simulate network design topologies and devices, network architectures (all these shapes are parts of network diagram tool ConceptDraw DIAGRAM).

Relationships Analysis

Relationships Analysis. Relations Diagram - factors analysis, factors relations. Create Relations Diagram with ConceptDraw DIAGRAM.
The Seven Management and Planning Tools is a tool for Interaction diagram drawing. This diagram identifies causal relationships. Determine what factors are causes and which factors are effects. Interaction diagram helps establish KPIs to monitor changes and the effectiveness of corrective actions in resolving the problem.

Watercraft - Design Elements

The vector stencils library Watercraft contains clipart of ships, boats, yachts, submarines for ConceptDraw DIAGRAM diagramming and vector drawing software.
Use it to draw illustrations of vessels and water transport over a sea, ocean, lake, canal, river.

Cisco Security. Cisco icons, shapes, stencils and symbols

The ConceptDraw vector stencils library "Cisco Security" contains 16 symbols of security devices and equipment for drawing the computer network diagrams using the ConceptDraw DIAGRAM diagramming and vector drawing software.

Data Flow Diagrams

Data Flow Diagrams (DFDs) are graphical representations of the "flow" of data through an information system. Data flow diagrams can be used for the visualization of data processing. ConceptDraw DIAGRAM extended with Data Flow Diagrams Solution is a powerful data flow diagramming application that allows you quickly create any Data Flow Diagrams including the data storages, external entities, functional transforms, data flows, as well as control transforms and signals.

UML Use Case Diagram Example. Social Networking Sites Project

UML Diagrams Social Networking Sites Project. 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 Facebook Socio-health system and is used at the projection and creating of the social networking sites.

Program Evaluation and Review Technique (PERT) with ConceptDraw DIAGRAM

PERT Diagram is a more realistic approach of a project's time estimate analysis. After PERT chart was constructed user can discover the shortest possible duration for entire project timescale. The project timeline is the longest chain that might be taken with connected tasks on the PERT Diagram. Completion of serial tasks need to be accomplished in a presented order. At a project timeline can be independent tasks that not linked with main sequence they are called parallel tasks. PERT diagram is more suitable for Critical Path Analysis than Gantt chart for the reason that it undoubtedly better determine task dependencies. Project managers customarily utilize both methodologies.
