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.

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 PRO.

How to Create a Business Process Diagram

An overview of any business process includes the description of the steps needed to implement any business task. The best approach to business process designing and analyzing is to depict visually the steps of business process in a form of business process diagram. Designing a Business Process diagram includes many different and specific elements that can be managed using ConceptDraw PRO. The ability to create Business Process diagrams according to the BPMN 2.0 is provided by the Business Process Model and Notation solution.

Basic Flowchart Symbols and Meaning

Flowchart Symbols and Meaning - Provides a visual representation of basic flowchart symbols and their proposed use in professional workflow diagram, standard process flow diagram and communicating the structure of a well-developed web site, as well as their correlation in developing on-line instructional projects. See flowchart's symbols by specifics of process flow diagram symbols and workflow diagram symbols.

How to Draw Geometric Shapes in ConceptDraw PRO

Knowledge of geometry grants people good logic, abstract and spatial thinking skills. The object of study of geometry are the size, shape and position, the 2-dimensional and 3-dimensional shapes. Geometry is related to many other areas in math, and is used daily by engineers, architects, designers and many other professionals. Today, the objects of geometry are not only shapes and solids. It deals with properties and relationships and looks much more about analysis and reasoning. Geometry drawings can be helpful when you study the geometry, or need to illustrate the some investigation related to geometry. ConceptDraw PRO allows you to draw plane and solid geometry shapes quickly and easily.

IDEF1X Standard

Use Case Diagrams technology. IDEF1x standard - for work with relational data bases. IDEF1x standard is meant for constructing of conceptual schemes which represent the structure of data in the context of the concerned system, for example, a commercial organization.

Bubble diagrams in Landscape Design with ConceptDraw PRO

Creation of a bubble diagrams in ConceptDraw is an easy task as you can use the ready scanned location plan instead of plotting paper and paper location plan. Besides scanning of the ready paper location plan you can easy create it using special ConceptDraw libraries and templates for creation room plans and location plans.

Electrical Symbols — Switches and Relays

In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high-voltage circuits in electrical substations.

26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
