Zusammenfassung:A method of managing a collection of members, wherein each member has data preserved in a finite data storage and each member belongs to a different data group of a temporal data store with which the finite data storage is associated, includes the step of deleting the oldest member of the collection upon the addition of a new member to the collection when the number of members of the collection exceeds a predetermined maximum number. The new member of the collection may be added to the collection after a member is deleted if the predetermined maximum number otherwise would be exceeded or, alternatively, the new member of the collection may be added to the collection, the predetermined maximum number of member then exceeded, and a member then deleted.
