a relational storage scheme suitable for derived views
A physical storage scheme used within a relational DBMS is described. The storage scheme is network in nature. The scheme implements physical linkage through shared attributes and enables data duplication to be eliminated. It results in a homogeneous structure for both permanent and temporary relations, and it is convenient for implementation of dynamic derived relations and supportability of updates by means of derived views. Our relational DBMS language incorporates unique features to facilitate the above objectives. These features make the user aware of the natural consequence of his data base.
