Abstract:Redundant network structures allow efficient retrievals. Procedures to design network structures that allow efficient retrievals [9] add redundancies into network structures. However, as redundancies increase, costs of updates increase. When network structures are redundant, costs of updates include costs of updating original data, checking consistencies, and updating derived data. This paper presents the super-key condition to reduce the costs of checking consistencies in redundant network structures.First, c… Show more
