ERD Symbols and Meanings

Entity Relationship Diagram Symbols and Meaning - crow's foot notation

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 PRO.

How to Build an Entity Relationship Diagram (ERD)

Entity-Relationship Diagram (ERD)

An Entity-Relationship Diagram (ERD) is a visual presentation of entities and relationships. That type of diagrams is often used in the semi-structured or unstructured data in databases and information systems. At first glance ERD is similar to a flowch

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 PRO.

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.

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 PRO 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.

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.

How to Add a Bubble Diagram to MS Word

A bubble diagram is used the same purpose as a scatter diagram, but in the case, if the data has three dimensions, each of that containing the set of values. A bubble chart is a diagram in which the data points are replaced with bubbles, and the size of the bubbles represents some additional dimension of the data. A bubble chart does not have the axis. The sizes of the bubbles are determined by the values in the third dimension. Any additional information about the entities beyond their three primary dimensions can be depicted by rendering bubbles in colors and patterns that are selected in a certain way. The legend containing the further information can be added to a bubble diagram. ConceptDraw PRO allows you to easily create various business management and marketing charts, including bubble diagrams and then add them to a MS Word document.
