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.

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.

But anyone have an ERD symbols quick reference? Detailed reference information for them is represented at the tables.
The vector stencils library "Logical symbols" contains 49 logical symbols for drawing logical network topology diagrams.
"Logical topology, or signal topology, is the arrangement of devices on a computer network and how they communicate with one another. How devices are connected to the network through the actual cables that transmit data, or the physical structure of the network, is called the physical topology. Physical topology defines how the systems are physically connected. It represents the physical layout of the devices on the network. The logical topology defines how the systems communicate across the physical topologies.
Logical topologies are bound to network protocols and describe how data is moved across the network. ... EXAMPLE : twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's token ring is a logical ring topology, it is physically set up in star topology." [Logical topology. Wikipedia]
The icons example "Logical symbols - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

Flowchart design. Flowchart symbols, shapes, stencils and icons

A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds - flowchart symbols, and their order by connecting them with arrows.
Mavericks have always desired to stand apart and gorgeous design is the recipe for that. Any business graphic document will be more understandable if will use an expository color scheme for their parts. Flowchart design makes versatile presenting and explaining of the process and gives a fresh view that distinguishes it from black and white flowcharts on a paper. Workflow diagram or process flow diagrams become more understandable to ordinary people when it use minimum symbols and special signs.
The best design can be accomplished by starting from any of the suitable Conceptdraw examples. Pick one of them and begin to input proper text into each Flowchart symbols and shapes. Apply less colors in the document and don't turn into rainbow your diagram, three or four will be enough, also note that business process flowchart may not contain bright color hues. The next clue is to use identical colors for same flowchart shape types.

Entity Relationship Diagram - ERD - Software for Design Crows Foot ER Diagrams

Crow's Foot notation was proposed by Gordon Everest. According to this notation, the entity is represented by rectangle, relation is depicted by line which ties two entities involved in a relationship. Entity-relationship diagrams based on both Chen's and Crow's Foot notations, can be easily drawn using the ConceptDraw DIAGRAM ERD diagrams software tools for design element Crow's Foot and Chen from Entity-Relationship Diagram (ERD) solution.
