In IBM® Rational® ClearQuest® an entity may have history information associated with it. Each record has a history field, and this field can have multiple history entries. Each history entry is a line of text describing the modification. All history objects are read-only, because the history entries for a data record are created automatically by ClearQuest.
The Histories object is a container object that stores one or more History objects. A Histories object is always associated with a single HistoryField object.
