periodic group

(database)
(PE) Groups of logically related fields which occur multiple times within a group.

Periodic groups are a non-relational technique. An example of a PE would be for storing the history of a person's name changes, where name was kept in logically related fields such as surname, first name and middle name - with the person having changed their name more than once.
