ERD Symbols and Meanings

Entity Relationship Diagram Symbols and Meaning - crow's foot notation
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 PRO.

Types of Flowcharts

Types of Flowcharts
A Flowchart is a graphically representation of the process, algorithm or the step-by-step solution of the problem. There are ten types of Flowcharts. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design the Flowchart of any of these types.

Data Flow Diagram (DFD)

Data Flow Diagram (DFD)
This example is created using ConceptDraw PRO enhanced with solution Data Flow Diagrams. This diagram shows one of the business processes to simplify and accelerate understanding, analysis, and representation.
"Classic TQM Tools ...
Flow Charts Pictures, symbols or text coupled with lines, arrows on lines show direction of flow. Flowcharting enables
modeling of processes; problems/ opportunities and decision points etc. It develops a common understanding of a process by those in

The vector stencils library TQM diagrams contains 58 symbols for drawing total quality management (TQM) flow charts using the ConceptDraw PRO diagramming and vector drawing software.
The example "Design elements - TQM diagram" is included in the Total Quality Management (TQM) Diagrams solution from the Quality area of ConceptDraw Solution Park.

Used Solutions
The vector stencils library "TQM diagrams" contains 58 TQM symbols. Use it in business process re-engineering, total quality management, continuous improvement, and quality solutions to draw cause-and-effect diagrams, top-down, and cross-functional process flow charts in the ConceptDraw PRO diagramming and vector drawing software extended with the Total Quality Management (TQM) Diagrams solution from the Quality area of ConceptDraw Solution Park.
