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.

ER Diagram for Cloud Computing

The entity–relationship (ER) model is a data model that lets graphically represent the information system and depict the relationships between people, objects, concepts, places, and events within a given system. It is also convenient to use the ER Diagram for Cloud computing representation and description the Cloud computing architecture, design them with pleasure using the extensive tools of the Cloud Computing Diagrams solution from the Computers and Network area of ConceptDraw Solution Park.

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.

Entity Relationship Diagram Software

The world-best Entity Relationship Diagram software suitable for professional ERD drawing is ConceptDraw DIAGRAM software extended with the Entity-Relationship Diagram (ERD) solution. This solution contains all libraries, templates and samples you may need for professional ERD drawing.

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 - ERD - Software for Design Chen ER Diagrams

The Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park extends ConceptDraw DIAGRAM vector graphics and diagramming software with the ability to describe a database using the Entity-Relationship (Chen) model. Use it for design your ERDs and verify that ConceptDraw DIAGRAM offers the best ERD diagrams software tools for design element Chen notation.

ER Diagram Styles

When creating ER diagrams, you can apply different color ER diagram styles and also notation styles. ConceptDraw DIAGRAM enhanced with Entity-Relationship Diagram (ERD) Solution gives the ability to draw visual and attractive ER Diagrams using the style icons from Crow’s Foot notation and Chen's notation professionally designed and offered by ERD Chen's Notation and ERD Crow’s Foot Notation libraries.

ConceptDraw DIAGRAM Database Modeling Software

ConceptDraw DIAGRAM is a very easy-to-use and intuitive database design tool which can save you hundreds of work hours. See database diagram samples created with ConceptDraw DIAGRAM database modeling database diagram software.

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.

Blueprint Software

The blueprints are the set of drawings used by architects and builders in the process of construction of the buildings. The blueprints represent the top views on the buildings (homes, offices, etc.). They are drawn in the scale and use the special blueprint symbols and blueprints codes. Earlier the blueprints wer printed on the special paper and was blue.
It's very easy, quick and convenient to draw the professional looking blueprints in ConceptDraw DIAGRAM diagramming and vector drawing software.

COM and OLE Diagram

The vector stencils library COM and OLE from the solution Software Engineering contains 15 symbols of the COM and OLE objects for ConceptDraw DIAGRAM diagramming and vector drawing software. The Software Engineering solution is contained in the Software Development area of ConceptDraw Solution Park.

Multi Layer Venn Diagram. Venn Diagram Example

To visualize the relationships between subsets of the universal set you can use Venn diagrams. To construct one, you should divide the plane into a number of cells using n figures. Each figure in the chart represents a single set of, and n is the number of represented sets. Splitting is done in a way that there is one and only one cell for any set of these figures, the points of which belong to all the figures from the set and do not belong to others. The plane on which the figures are represented, is the universal set U. Thus, the point which does not belong to any of the figures, belongs only to U.
