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.

Workflow Diagram Examples

ConceptDraw DIAGRAM - workflow software extended with the Workflow Diagram solution provides a complete set of samples, templates and features help you to draw diagrams faster. A workflow software you use for drawing workflow diagrams and business process flow diagrams should provide a wide set of examples allows you get closer with workflow diagrams, learn symbols meaning, find appropriate layout and design, and then start drawing your own workflow diagram masterfully. Workflow diagrams used for orchestrating organizational processes between company departments and humans, so critical process diagrams used to train many people to interact must be clear and professional to convey an idea from a view. Thats a reason we created a lot workflow symbols and workflow icons collected them into special Workflow Diagram solution in ConceptDraw Solution Park.

Database Flowchart Symbols

Data base diagrams describes inter-related data and tables. It describes roles and relationships, internal and external dependencies, data exchange conventions and structures of knowledge domain.
ConceptDraw Software provides number of data-base chart libraries including major 49 vector symbols. Use these DFD flowchart symbol libraries to design data-base structure and models, use it to design data base process-oriented models, or simple data-oriented models. The are special drawing tools for making data flowcharts, data process diagrams, structured analysis diagrams, and information flow diagrams.

ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw DIAGRAM.

Electrical Symbols — Semiconductor

Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high resistance — higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics.

UML Component Diagram library contains 36 shapes

UML Diagram

UML defines 13 types of diagrams: class (package), object, use case, sequence, collaboration, component, state machine, timing, interaction overview, composite structure, activity, and deployment.
Create unified modeling language (UML) diagrams with ConceptDraw.

Electrical Symbols — Transformers and Windings

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force within a conductor which is exposed to time varying magnetic fields. Transformers are used to increase or decrease the alternating voltages in electric power applications.
