ERD Symbols and Meanings

This vector stencils library contains 26 IDEF0 diagram symbols.
Use it for business process modeling with IDEF0 diagrams using ConceptDraw PRO diagramming and vector drawing tools.
The vector stencils library "IDEF0" is included in the IDEF Business Process Diagrams solution from the Business Processes area of ConceptDraw Solution Park.

The vector stencils library "IDEF0" contains 26 IDEF0 diagram symbols.
Use it for business process modeling with IDEF0 diagrams.
"The IDEF0 model ... is based on a simple syntax. Each activity is described by a verb-based label placed in a box. Inputs are shown as arrows entering the left side of the activity box while output are shown as exiting arrows on the right side of the box. Controls are displayed as arrows entering the top of the box and mechanisms are displayed as arrows entering from the bottom of the box. Inputs, Controls, Outputs, and Mechanisms are all referred to as concepts.
- Arrow: A directed line, composed of one or more arrow segments, that models an open channel or conduit conveying data or objects from source (no arrowhead) to use (with arrowhead). There are 4 arrow classes: Input Arrow, Output Arrow, Control Arrow, and Mechanism Arrow (includes Call Arrow). See Arrow Segment, Boundary Arrow, Internal Arrow.
- Box: A rectangle, containing a name and number, used to represent a function.
- Context: The immediate environment in which a function (or set of functions on a diagram) operates.
- Decomposition: The partitioning of a modeled function into its component functions.
- Fork: The junction at which an IDEF0 arrow segment (going from source to use) divides into two or more arrow segments. May denote unbundling of meaning.
- Function: An activity, process, or transformation (modeled by an IDEF0 box) identified by a verb or verb phrase that describes what must be accomplished.
- Join: The junction at which an IDEF0 arrow segment (going from source to use) merges with one or more other arrow segments to form a single arrow segment. May denote bundling of arrow segment meanings.
- Node: A box from which child boxes originate; a parent box. See Node Index, Node Tree, Node Number, Node Reference, Diagram Node Number." [IDEF0. Wikipedia]
The shapes example "Design elements - IDEF0" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the solution "IDEF Business Process Diagrams" from the area "Business Processes" of ConceptDraw Solution Park.

The vector stencils library "Line Graphs" contains 4 chart templates. Use it to design your line charts in ConceptDraw PRO diagramming and vector drawing software.
"A line chart or line graph is a type of chart which displays information as a series of data points connected by straight line segments. It is a basic type of chart common in many fields. It is similar to a scatter plot except that the measurement points are ordered (typically by their x-axis value) and joined with straight line segments. A line chart is often used to visualize a trend in data over intervals of time – a time series – thus the line is often drawn chronologically." [Line chart. Wikipedia]
