Multivalued attribute ER diagrams for companies are called ER diagrams and Entity Relationship Models. An ERD depicts the relationships between entities in a database, such as people, things, or concepts. A multivalued attribute ER diagram for companies will frequently display the attributes of these entities. An ER diagram can depict the logical structure of databases by defining the entities, their characteristics, and the relationships between them. This is useful for engineers who want to either document an existing database or sketch out a design for a new database. When a business uses an ER diagram to document existing databases, it can help troubleshoot logic or deployment issues, identify inefficiencies and help improve processes.
