Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ER Diagram, E-R Diagram, ERD) is a time-tested and widespread software development and software engineering method for data modeling, illustrating the logical structure of databases and system design. For ERDs construction are used three basic elements: entities, attributes, and relationships. Chen's notation for ERD supposes the use of rectangles (boxes) to represent entities and diamonds to depict relationships between first-class objects. This notation is popular when creating conceptual data models of information systems. Another standardized notation for ER diagrams is Crow's foot notation. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram software engineering provides the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park for instantly describing databases using ERDs of Crow’s Foot and Chen’s notations. Use the predesigned vector elements for both these notations from 2 libraries included to Entity-Relationship Diagram (ERD) solution.

Entity Relationship Diagram Examples

Creation of Entity-Relationship (ER) model is a visual representation the structure of a business database, where data equates to entities or objects, which are linked by defined relationships expressing dependencies and requirements. By the nature, the ER model is an abstract visualization, a first step in design process towards creating a logical and functional database. ConceptDraw DIAGRAM professional software gives the ability to effectively describe a database using the Entity-Relationship model. Included to ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of predesigned vector icons advocated by Chen's and Crow’s Foot notations that both can be used for data modeling and describing a database. Entity-Relationship Diagram (ERD) solution includes also helpful templates and incredibly large collection of varied Entity Relationship Diagram examples and samples offered at ConceptDraw STORE. Each of them can be used to develop your own model of a database of arbitrary complexity.

UML Deployment Diagram Example - ATM System UML diagrams

The UML Deployment Diagram is used for visualization of elements and components of a program, that exist at the stage of its execution. It contains graphical representations of processors, devices, processes, and relationships between them. The UML Deployment Diagram allows to determine the distribution of system components on its physical nodes, to show the physical connections between all system nodes at the stage of realization, to identify the system bottlenecks and reconfigure its topology to achieve the required performance. The UML Deployment diagram is typically developed jointly by systems analysts, network engineers and system engineers. ConceptDraw DIAGRAM diagramming and vector drawing software with Rapid UML solution from Software Development area of ConceptDraw Solution Park perfectly suits for designing different types of UML diagrams, including the UML Deployment Diagrams. There are included a lot of design elements, templates, examples and samples, among them an example of work of ATM (Automated Teller Machine) banking system.

Fishbone Diagram Example

Fishbone Diagram, also referred as Cause and Effect diagram or Ishikawa diagram, is a fault finding and problem solving tool. Construction of Ishikawa diagrams is quite complicated process and has a number of features. Fishbone Diagrams solution included to ConceptDraw Solution Park contains powerful drawing tools and a lot of examples, samples and templates. Each Fishbone diagram example is carefully thought-out by experts and is perfect source of inspiration for you.
