ER-model based diagrams (ERD) consist of these main components: relation, entity and attributes. To be able to create such diagram, you have to mention the entities with their names presented in a form of a rectangle and the relations in a way of non-directional line connecting two entities. To help you to create this chart, we developed ConceptDraw STORE product full of libraries with vector elements you can use for your flowchart. Also we provide you with Solutions section on this site where you can find the numerous stencil libraries, samples and examples to simplify your work with software called ConceptDraw DIAGRAM which is the only one offering that many symbols and templates for making professionally looking smart and mature diagrams.
