Abstract

Many reports have been published on the design strategies employed in the development of multidatabase systems. This paper examines some of these strategies and compares the design of the ADDS system to other efforts in the development of multidatabase systems. There are a number of interesting issues that arise when considering the design of a distributed multidatabase system. These include: (1) the levels of update control for the supported physical databases, (2) the cooperation of the global and local concurrency control schemes, (3) the treatment of concurrency control of a partially replicated distributed multidatabase directory, (4) reduced data transmission with enhanced semijoin algorithms and localized processing of intermediate query results, and (5) the network architecture required to support a distributed multidatabase system.
