Explain multivalued attributes with the help of examples. How are multivalued attributes indicated in the Chen Entity Relationship model?
Multivalued attributes are attributes that can have many values. For instance, a person may have several college degrees, and a household may have several different phones, each with its own number. Similarly, a car's color may be subdivided into many colors for the roof, body, and trim. In the Chen Entity Relationship model, multivalued attributes are shown by a double line connecting the attribute to the entity.
