Adaptive protocols for managing replicated distributed databases

The author proposes a family of adaptive protocols for managing replicated databases. Adaptive protocols use information about the system configuration to determine how operations are executed. Special system transactions are executed to maintain this information in view objects. The author proposes using static as well as dynamic methods to execute both system and user transactions. This results in a modular methodology for designing four different protocols. Two of these protocols are new and present the system designer with several alternatives when compared with the previously known protocols
