Entity-Relationship diagram: Entity-Relationship (ER) diagram is the method to represent the relational database using graphical form. This graphical representation shows only primary elements such as records, types, attributes, relationships between entities, and so on. The graphical representation of the ER diagram clearly describes the relationship among entities. In the diagram, every connector is labeled. On one side it is represented by the value 1, and on the other side it is labeled with the value “M”. This labeling is referred to as “cardinality constraint” of the relationship.
