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.

EIGHT RELATED HOW TO's:

Entity Relationship Diagram Software Engineering →

While designing a conceptual data model, you should use appropriate software. For instance, ConceptDraw DIAGRAM is a user-friendly ER diagram tool that has a lot of samples and templates to facilitate your work. A clear entity-relationship diagram helps to define the relations between system’s components. Software engineering is the section of a computer science engaged to design, realization, and support of complex software products. An ERD is a data modeling method that is widely applied in the software engineering practice. Commonly it is used for developing a structure of a a relational database. An entity relationship diagram is helpful for structuring and organizing databases that can be modeled using a relational structure. An entity relationship diagram is designed to depicts the interrelationships within the sets of entities which are accumulated in the database. Each entity represents a particular component of a data. Thus, ER diagrams depicts the logical structure of databases. ConceptDraw ER Diagrams solution provides software engineers with the professional tool for making entity-relationship diagrams.Entity Relationship Diagram Software Engineering *
