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.
Entity Relationship Diagram Software Engineering
Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for data modeling, system design and illustrating the logical structure of databases.Professional ERD drawing is an essential software engineering method for database modeling. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram Software Engineering offers the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park.
Entity-Relationship Diagram
Entity Relationship Diagram (ERD) is the world-known way to show the logical structure of databases in visual manner. The best software tool for drawing Entity-Relationship Diagram is ConceptDraw DIAGRAM vector graphics software with Entity-Relationship Diagram (ERD) solution from Software Development area which gives the ability to describe a database using the Entity-Relationship model. The vector graphic diagrams produced using this solution can be successfully used in whitepapers, presentations, datasheets, posters, or any technical materials.UML Diagram
UML defines 13 types of diagrams: class (package), object, use case, sequence, collaboration, component, state machine, timing, interaction overview, composite structure, activity, and deployment.Create unified modeling language (UML) diagrams with ConceptDraw.

Entity-Relationship Diagram(ERD) solution from the Software Development area supplies the ConceptDraw DIAGRAM with icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

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.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.

UML Class Diagram Generalization Example UML Diagrams
This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Class Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.This sample describes the use of the classes, the generalization associations between them, the multiplicity of associations and constraints. Provided UML diagram is one of the examples set that are part of Rapid UML solution.
The vector stencils library "Data flow diagram (DFD)" contains 15 DFD elements.
Use it for process-oriented models, data-oriented models, data flowcharts, data process diagrams, structured analysis diagrams, and information flow diagrams in the ConceptDraw PRO diagramming and vector drawing software extended with the Data Flow Diagrams solution from the Software Development area of ConceptDraw Solution Park.
