entity-relationship diagram, ER-diagram, database 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

You dream to find powerful software for easy designing Network Security Architecture Diagram? We recommend to use ConceptDraw DIAGRAM extended with Network Security Diagrams Solution from the Computer and Networks 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.

Data structure diagram with ConceptDraw DIAGRAM

Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw DIAGRAM.

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.

ConceptDraw Arrows10 Technology

Imagine the diagram which is looking smart. That is how ConceptDraw Arrows10 Technology or Smart connectors work.

Thanks to auto-routing feature connectors flow around objects. But if you want some background objects that the connectors flow through - that is also possible to do.

ConceptDraw Arrows10 Technology

When using a shapes′ center connection the connection becomes dynamic, the connector will trace the contour of the object, when moving the object inside your diagram.

Using any other connection point provides a static connection, when you move connected objects the connector stays attached to the same point.

UML Block Diagram

Use Case Diagram Taxi Service UML. This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.
This sample shows the work of the taxi service and is used by taxi stations, by airports, in the tourism field and delivery service.

ConceptDraw Arrows10 Technology

How should diagramming software work? The answer is - Fast and easy. "Tree"- mode drawing works like that. Just select objects in your drawing and press Tree or Chain button to connect all of them just in one click. Your diagram looks professional and it took only a moment to draw.

Guesthouse Network

This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
Computer and Networks solution provides examples, templates and vector stencils library with symbols of local area network (LAN) and wireless LAN (WLAN) equipment.

ConceptDraw Arrows10 Technology

New Smart connectors in ConceptDraw DIAGRAM now have an auto-routing feature. This means that connectors always find the optimal route between objects and automatically recalculate that path when moving these objects.

You don't have to think about your connectors, they think for you.
