Design Element: Crows Foot
for Entity Relationship Diagram - ERD

Entity-relationship Diagram (ERD) is a perfect tool which lets execute the detalization of data warehouse for designed system, as well as documenting the entities of the system and their interactions each other, including the identification of important domain objects (entities), the properties of these objects (attributes) and their relationships to other objects.

Creating an ERD requires choosing a specific set of notations that best serve the specific database being designed. Chen’s original notation had a linguistic approach, where boxes representing entities could be thought of as nouns, and the relationships between them were in verb form, shown on a diagram as a diamond.

Eventually Chen’s style was adapted into the Crow’s Foot notation, where relationships were shown as single labeled lines – this quickly became the popular standard, due to improved readability on diagrams, with a more efficient use of space on the page.

ConceptDraw DIAGRAM software extended with Entity-Relationship Diagram (ERD) solution from Software Development area of ConceptDraw Solution Park allows you to draw ER diagrams for depicting a database using the ERD diagram design element Crow's Foot - Crow′s Foot notation icons.

Data Flow Diagram Symbols. DFD Library →

Any information system receives data flows from external sources. In order to visualize them there is a list of data flow diagram symbols that describes how the system components cooperate. If you want to create a data flow diagram, ConceptDraw DIAGRAM Solution Park has DFD Library that contains both Yourdon and Gane-Sarson notations. This figure shows the content of vector libraries, delivered with ConceptDraw solution for data flow diagram (DFD). There are three libraries composed from about 50 vector objects used to make data flow diagrams. They include a complete set of objects utilized by Yourdon-Coad and Gane-Sarson notations - two primary notations that are apply for data flow diagramming. Also, one can discover additional "Data flow diagram (DFD)" library that provides a data flow diagram elements for designing level 1 and context-level data flow diagrams.Data Flow Diagram Symbols.

Data Flow Diagram (DFD) →

In software engineering, it is important to understand how the system would cooperate with external sources, like data sources. To give this information a visual representation, data flow diagrams (DFD) were used for years. The entire system is usually divided into smaller ones, and all of them process data flows in appropriate ways. The visualizing business processes which engages the data transfer, is commonly preformed using DFDs (data flow diagrams). DFD is used to show the data flow processing and transformation. This DFD represents the electronic system of a customer purchase. It was created using Gane/Sarson notation. Data flow diagrams helps you to sort through and clarify transferring process making it available for analysis, and representation. ConceptDraw DFD solution introduces the vector library, containing the full set of icons from DFD notations.Data Flow Diagram (DFD) *
