Abstract
A shared tuple method for storing data in a database which supports modification of view relations without causing anomalous changes to logically unrelated tuples in the same or other relations. A generated key is generated by the database which uniquely identifies data in a child tuple. As a result, virtual parent relations are referenced by an original primary key, but has its underlying attribute values stored in one or more secondary relations whose access is gained through stored generated keys. The application interface is unaffected, because the system transparently pieces together the virtual relation from the primary and one or more secondary relations.
