Entity Relationship Diagram Software Engineering

Entity Relationship Diagram (aka ERD, ER Diagram, E-R Diagram) is a well-tried software engineering tool for data modeling, system design and illustrating the logical structure of databases. Introduced by Peter Chen the ER modeling technique is now successfully used in software development, when creating conceptual data model of an information system.

There are used three basic elements for ERDs construction: entities, attributes, relationships. Chen's notation for ERD assumes the use of rectangles to represent entities and diamonds to represent relationships between first-class objects. Another popular notation for ER diagrams is Crow's foot notation.

Professional ERD drawing is an essential software engineering method for database modeling. ConceptDraw DIAGRAM as a powerful Entity Relationship Diagram software engineering offers the tools of Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park.

Electrical and Telecom Plan Software →

While studying, many of the students encounter the necessity of remaking class projects, over and over. To facilitate this process you can use special electrical and telecom plan software, which helps altering projects in several clicks. Using templates will fasten your work, and you will have more free time. This sample represents an electrical and telecommunication floor plan. Electrical and telecom floor plans contain a floor plan , on which imposed the layout of electrical, and telecommunications equipment. They shows electrical and telecom details regarding the current floor of a building: lightening, fixtures, wires, outlets, circuit panels, etc. Using of standart notation of electrical and telecommunication symbols makes the plan understandable for engineers, architects, constructors, specialist in electricity and telecommunications.Electrical and Telecom Plan Software
