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.

Entity Relationship Diagram Software for Mac

One of the most popular semantic data models is the "entity-relationship" model (often called ER-model). Most of the modern approaches to the database (mainly relational) design are based on the usage of different versions of ER- model. Domain modeling is based on the use of graphic charts, including a small number of heterogeneous components. The simplicity and the presentation clarity of the conceptual basis of these ER-model schemes led to its widespread deployment in the CASE-systems that support automatic design of relational databases.
A relation is a graphically depicted association between two entities. As well as the entity, a relation is a typical concept, all instances of the linked entity types are subject to the rules established by the connecting. Therefore, it is more correct to speak about the relationship type made between types of entities and about the instances of relationship types made between instances of the entity type. In common ER-model this association is a
