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.

Martin ERD Diagram

The vector stencils library Crow's Foot Notation from the solution Entity-Relationship Diagrams (ERD) contains specific symbols of the Crow's foot notation such as relationship symbols and entity symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Entity-Relationship Diagrams (ERD) solution is contained in the Software Development area of ConceptDraw Solution Park.

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.

Software and Database Design with ConceptDraw DIAGRAM

ConceptDraw DIAGRAM is a perfect tool for designing and planning tasks such as:
UML diagramming; designing and prototyping Graphical User Interface (GUI); flowcharts, data flow diagrams; database and ERD diagramming (Chen ERD, Database Model diagram, Express-G, Martin ERD, ORM Diagrams and more); SSADM diagrams, Booch diagrams, Nassi-Shneiderman diagrams with special flowchart symbols.

Components of ER Diagram

ConceptDraw gives the ability to draw ER diagram (ERD) for visual describing database using the entity relationship symbols, work flow shapes, entity relationship stencils. Entity-Relationship model making possibility to describe a database using the components of ER Diagram in which in the tables data can be the point to data in other tables - for instance, your entry in the database could point to several entries.

E-R Diagrams

Complexity of databases increases day by day, due to this the Entity relationship models and E-R diagrams become more and more popular, and now are an important part of database design. E-R diagrams created at ConceptDraw DIAGRAM allow visually and graphically represent structure and design of databases.

Data Flow Diagram

Data flow diagram (DFD) is the part of the SSADM method (Structured Systems Analysis and Design Methodology), intended for analysis and information systems projection. Data flow diagrams are intended for graphical representation of data flows in the information system and for analysis of data processing during the structural projection. Data flow diagram often used in connection with human process and can be displayed as workflow diagram. The critical Process Flow Diagram is another flowchart technique for designing data flow in connection with organizational processes. The critical Process flow diagram may use different range of symbols than a classic workflow diagram.

ER Diagram Programs for Mac

ConceptDraw DIAGRAM compatible Mac OS X software extended with powerful Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park is one of the famous ER Diagram Programs for Mac. It gives the perfect ability to draw ER diagrams for visually describing databases with Chen's and Crow's Foot notation icons.

Data Modeling Diagram

The vector stencils library Activity diagrams from the solution Rapid UML contains specific data modeling symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Rapid UML solution is contained in the Software Development area of ConceptDraw Solution Park.

DFD Library System

Use the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park to draw your own context-level DFDs using the ConceptDraw DIAGRAM diagramming and vector drawing software.

Block Diagram

The vector stencils libraries: Block Diagrams, Blocks with Perspective, Callouts, Connectors, Raised Blocks from the solution Block Diagrams contain specific block diagram symbols such as arrows, input/output symbols, start/end symbols, processing symbols, conditional symbols, commenting symbols, callouts, connectors, etc. for ConceptDraw DIAGRAM diagramming and vector drawing software. The Block Diagrams solution is contained in a "Diagrams" area of ConceptDraw Solution Park.
Use the libraries from the Block Diagrams solution to draw block diagrams for your business documents, presentations and websites in a few minutes.
