Software for diagramming

ConceptDraw PRO gives the ability to draw professional ER diagrams (ERD) for describing a databases visually with the Chen's and Crow’s Foot notation icons. Use for this the powerful tools of the Entity-Relationship Diagram (ERD) Solution from the Software Development Area for ConceptDraw Solution Park.

Entity-Relationship model making possibility to describe a database by abstract way. The data in database tables can be the point to data in other tables - for instance, your entry in the database could point to several entries.

What are Entity Relationship Diagrams?

Entity relationship diagram (ERD) is a graphical representation the logical structure of the relational databases, the entities and their relationships in a database. The ERDs are created in the process of the Entity-relationship modeling. It is the most important software engineering method for database modeling.

ERD contains three types of the elements: entities that represent the items on which people look for the information, attributes that represent the data related to the entities and relationships that assure a structure for the information.

There are several notations for drawing ERDs of any complexity, the most often are used the Chen's and Crow’s Foot notations.

Chen's notation represents entities as rectangles, and relationships appropriate for first-class objects as diamonds. If an entity set participates in a relationship set, they are connected with a line. Attributes are drawn as ovals and are connected with a line to exactly one entity or relationship set.

Example 2. Entity relationship diagram (ERD), Chen's notation

Crow's Foot notation uses boxes to represent entities, and lines between the boxes to represent relationships. Different shapes at the ends of these lines represent the cardinality of the relationship. Attributes of entity are drawn in the box that represents the entity.

ERD Symbols and Meanings
Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship. The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships. To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw PRO.  Read more... →

Entity-Relationship Diagram (ERD) with ConceptDraw PRO
Entity-Relationship Diagram (ERD) serves for detailed description of structures and databases. An ERD represents a diagram made up mainly of rectangular blocks (for entities, or data) linked with relationships. The links between the blocks describe relations between these entities. There are three types of relationships: one-to-one, one-to-many, many-to-many.

Entity Relationship Diagram Symbols
Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database. ERD symbols used for professional ERD drawing are collected in libraries from the Entity-Relationship Diagram (ERD) solution for ConceptDraw PRO.  Read more... →
