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.

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 Examples

Entity Relationship Diagram Examples
Create 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.

ConceptDraw DIAGRAM diagramming and vector drawing software gives the ability to describe a database using the Entity-Relationship model. 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.

ERD Symbols and Meanings

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.

An Event-driven Process Chain (EPC) - flowchart used for business process modelling

Event-Driven Process Chain flowcharts for improvement throughout an organisation.
ConceptDraw DIAGRAM is a software for making EPC flowcharts to provide business process modelling. Its excellent business process improvement tools.
The business processes modeling (BPM) flowchart sample "Event-driven process chain (EPC) diagram" was created on the base of illustration from "Methods for the specification and verification of business processes. 19 - Event-driven process chains. Roberto Bruni. 2011".
"An Event-driven Process Chain (EPC) is a
particular type of flow-chart that can be used for configuring an Enterprise Resource Planning (ERP) implementation.
Supported by many tools (e.g. SAP R/ 3).
EPC Markup Language available (EPML)
as interchange format. ...
EPC overview.
Important notation to model the domain aspects of business processes.
Rather informal notation.
EPC focus is on representing domain concepts and processes (not their formal aspects and technical realization).
It can be used to drive the modeling, analysis and redesign of business process." [cli.di.unipi.it/ ~rbruni/ MPB-12/ 19-EPC.pdf]
The event-driven process chain (EPC) diagram example was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Event-driven Process Chain Diagrams solution from the Business Processes area of ConceptDraw Solution Park.
