The creation of the Entity-Relationship (ER) model is a visual representation of the structure of a business database, where the data are equivalent to entities or objects, which are linked by defined relations that express dependencies and requirements. By nature, the ER model is an abstract visualization, a first step in the design process towards the creation of a logical and functional database. ConceptDraw Professional PRO software gives you the ability to effectively describe a database using the Entity-Relationship model. Included in ConceptDraw Solution Park, the Entity-Relationship Diagram (ERD) solution contains the set of vector predesigned icons defended by Chen and Crow's Foot notations, which can be used to model data and describe a database. Entity-Relationship Diagram (ERD) also includes useful templates and an incredible collection of various examples of entity relationship diagrams and samples offered in ConceptDraw Solution Browser. Each of them can be used to develop their own model of a database of arbitrary complexity.
