repeating group

database Any attribute that can have multiple values

associated with a single instance of some entity. For

example, a book might have multiple authors.

In order to represent such a relationship in a relationaldatabase, it would be converted to "first normal form" as the

first step in database normalisation. Each author of the

book would then appear in a separate row, each of which also

contained the book's primary key.
