This diagram represents the vector library of the Chen’s and Crow’s Foot notation icons for drawing ERD (entity-relationships diagram). ConceptDraw Entity Relationship Diagram solution delivers the ability to visualize databases structure on both Mac and PC. The "bricks" entity-relationships models are the entity, and the relation. An entity is represented by a rectangle comprising the entity name. It means an object, information about which should be available and stored. A relation is intended to show a relations between two entities. There are several types of relations between entities. To show there are a number of different symbols for the types of relationships.

The ability to describe a database using the Entity-Relationship model is delivered by the Sample 1. Entity relationship diagram (ERD), crow's foot notation .

This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.

An entity relationship diagrams look very simple to a flowcharts. The main difference is the symbols provided by specific ERD notations. There are several models applied in entity-relationship diagrams: conceptual, logical and physical. Creating an entity relationship diagram requires using a specific notation. There are five main components of common ERD notations: Entities, Actions, Attributes, Cardinality and Connections. The two of notations most widely used for creating ERD are Chen notation and Crow foot notation. By the way, the Crow foot notation originates from the Chen notation - it is an adapted version of the Chen notation.

Software for ER diagramming. ConceptDraw PRO allows to draw ER diagrams for visually describing a databases with the Crow’s Foot notation icons.

An entity-relationship (ER) diagram is used to show the structure of a business database. ERD represents data as objects (entities) that are connected with standard relationships symbols which Illustrate an association between entities. ERD, there is a wide range of ERD notations used by data bases architects for reflecting the relationships between the data entities. According to the crow’s foot notation relationships are drawn as single labeled lines designating a certain kinds of relationship. Crow foot notation is a most frequently used ERD standard, because of improved readability of diagrams, with a more accurate use of space on the page.

When designing an Entity-Relationship Diagram one need to use a certain notated symbols that were developed and standardized especially for databases description. First of them - the Chen’s notation had a linguistic origin. It includes rectangle boxes to show entities that may be described as nouns, and the relationships between them described as verbs depicted in a form of diamond. Finally the Chen’s notation was simplified up to the Crow’s Foot notation. It represents a relationship as labeled line. It is precisely this notation is shown in the given figure. ConceptDraw PRO together with its Entity-Relationship Diagram (ERD) solution is designed to support professionals who deals with creating ER diagrams using the element of both - Chen’s and Crow's Foot notations.

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.

ERD symbols used for professional ERD drawing are collected in libraries from the you own entity relationship diagrams using Chen's or crow's foot notations .

Entity Relationship Diagram describes data elements and their relationships within a database. There are a set of special symbols that depict each element of an entity relationship diagram. Entities - represents some stable components such as supplier, employee, invoice, client, etc. Relation symbols show how the entities interact. Attributes define characteristics of the relationships. Attributes can be one-to-one or many-to-many. Physical symbols is used in the physical models. They represent items such as fields, tables, types and keys. ERD physical symbols are the building material for the database. Notation lines are used to illustrate the relationships. The most common method is Crow’s Feet notation. You can use ConceptDraw Entity-Relationship Diagram (ERD) solution to represent a database using the Entity-Relationship model.
