3.3.3 Multi-Valued Attribute
Another type of non-simple attribute that has to be managed is called a multivalued attrib-
ute. The multi-valued attribute, as the name implies, may take on more than one value for
a given occurrence of an entity. For example, the attribute school could easily be multi-val-
ued if a person attends more than one school.
