Explain the purpose of an ER diagram in database design
The entity relationship (ER) diagram is the graphical representation technique used to depict a data model. Each entity in a ER diagram is named in the singular noun form such as Customer rather than Customers. The labeled line connecting two entities describes the nature of the association between them. This association is represented with a verb such as shipped, requests, or receives. The ER diagram also represents cardinality (the degree of association between two entities). Four basic forms of cardinality are possible: zero or one (0,1), one and only one (1,1), zero or many (0,M), and one or many (1,M). These are combined to represent logical associations between entities such as 1:1, 1:0,M, and M:M.
