Entity Relationship Diagram Examples
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.ConceptDraw gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram solution includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.
Example of DFD for Online Store (Data Flow Diagram)
Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.
Entity Relationship Software
Entity Relationship Diagrams (ERD) illustrate the logical structure of databases.The vector graphic diagrams produced when using the ConceptDraw ERD solution can be used in whitepapers, presentations, datasheets, posters, or any technical materials.
It is convenient to design ER Diagrams using ConceptDraw DIAGRAM software. ConceptDraw DIAGRAM extended with the Entity-Relationship Diagram (ERD) solution supports Chen's and Crow’s Foot notations that are often used to describe database structure.

Business Process Workflow Diagram is a professional visual tool that is widely applied for business development, business analysis, business process optimization and documenting business processes. Business Process Workflow Diagram lets depict in details the steps of business processes and flow of tasks between them, the execution of business processes, transfer of data and documents.The workflows on the Business Process Workflow Diagram are represented using the set of common symbols which let easy illustrate business processes and process flows, depict the start, all major steps and end of the process, what data are used by the process, how the data flow through the business areas within scope of our project, how the tasks are executed and by who, and how workers interact with each other.
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.26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM 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.
Fire Exit Plan. Building Plan Examples
In order to make it safe both for you and for your employees as well as your clients who come to pay you a visit time to time and who can get trapped in a building, especially if your office is in a high building on one of the top floors of it, then you must make the fire exit plan in case of fire enabling people to live the building on time avoiding being hurt, injured or even dead. For making such plan you can always use ConceptDraw DIAGRAM software which is one of the best drawing applications providing all of the necessary tools for making your own plans, including the fire exit ones.CCTV Network Example
