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.

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 DIAGRAM.
Workflow Diagram Data
Workflow Diagram created by using special software based on graphic mastering technology Arrows10. Its automatics follows the global concept of business graphics and diagramming. The practical effectiveness of Arrows10 technology used in ConceptDraw DIAGRAM are around the quick auto-arrows behaving as expected and connecting boxes of workflow diagram from workflow symbol to process flow symbol.ConceptDraw DIAGRAM is a workflow diagram software contains specific features help you to draw diagrams faster, such as RapidDraw, or Arrows10. There is also a rich set of samples and templates to give you an example of data may be visualized as workflow diagram.

This onion diagram sample was created on the base of the figure "Social Ecological Model (SEM)" illustrating the webpage "Cultural Competence" from the US Centers for Disease Control and Prevention (CDC) website.
"Why consider cultural competence?
It is important to communicate effectively to both the disparately affected population(s) of interest as well as other key stakeholders at the community, state, and national levels.
The diagram of the Social Ecological Model (SEM) ... depicts how health behaviors of an individual (inner oval) are influenced by the interpersonal, organizational, community, and public policy contexts and environment in which that person exists. Cultural context resides in the interpersonal band, making it a critical consideration when designing any communication plan. All obesity prevention communications should take the culture (e.g., language, thoughts, communications, actions, customs, beliefs, values, and institutions of racial, ethnic, religious, or social groups) of the target population into consideration to be effective. Interventions that successfully achieve this goal demonstrate cultural competence - behaviors, attitudes, and policies that come together in a system, agency, or among professionals to enable people to work effectively in a cross-cultural situation."

This marketing diagram sample depicts balanced scorecard strategy map.
It was redesigned from the Wikimedia Commons file: Strategy map.JPG. [commons.wikimedia.org/ wiki/ File:Strategy_ map.JPG]
"A strategy map is a diagram that is used to document the primary strategic goals being pursued by an organization or management team. It is an element of the documentation associated with the Balanced Scorecard...
Strategy maps show:
(1) Each objective as text appearing within a shape (usually an oval or rectangle).
(2) Relatively few objectives (usually less than 20).
(3) Objectives are arrayed across two or more horizontal bands on the strategy map, with each band representing a 'perspective'.
(4) Broad causal relationships between objectives shown with arrows that either join objectives together, or placed in a way not linked with specific objectives but to provide general euphemistic indications of where causality lies." [Strategy map. Wikipedia]

Data Flow Diagram Symbols. DFD Library
Data Flow Diagrams show information transfers and process steps of a system. The general concept is an approach of a depicting how occurs input in a system, further processes and what runs out. The aim of DFD is in accomplishing of understanding between developers and users. Data flow diagrams are maintained with other methods of structured systems analysis.Concept Maps
As concept map consists from conception-blocks and links between them, you can use ConceptDraw library objects and add to a document as much objects as you need. ConceptDraw tools let you to edit, group, move objects, change their appearance and add text signs and raster or vector pictures.ConceptDraw DIAGRAM diagramming and vector drawing software extended with Concept Maps Solution from the "Diagrams" Area is effective tool for creating professional looking Concept Maps.
Influence Diagram
This sample shows the Influence Diagram. It was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Basic Diagramming Solution from the Universal Diagramming area of ConceptDraw Solution Park.Influence diagram represents the directed acyclic graph with three types of nodes and three types of arcs that connect the nodes. Decision node is drawn as a rectangle, Uncertainty node is drawn as an oval, Value node is drawn as an octagon.
