This company's ER diagram model with multivalued attributes uses a diagram to describe a database's structure, known as an Entity Relationship Diagram (ER Diagram). A company ER diagram model with multivalued details is a database design or blueprint that can be later implemented as a database. The entity set and relationship set are the two main components of the E-R model. An ER diagram depicts the relationship between entity sets. In terms of DBMS, an entity is a table or a feature of a table in a database, so an ER diagram shows the complete logical structure of a database by establishing relationships between tables and their attributes.
