Entity Relationship Diagram Software

Software for diagramming

ConceptDraw DIAGRAM 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.

When it comes to system construction, a class diagram is the most widely used diagram. UML Class Diagrams is a type of static structure diagram that is used for general conceptual modeling of the systematics of the application. Such a diagram would illustrate the object-oriented view of a system. The object orientation of a system is indicated by a class diagram. It describes the structure of a system by showing the general issues,classes of a system, attributes, operations, interfaces, inheritance, and the relationships between them.UML Class Diagram Notation *
