Abstract

The correct and effcient management of data in distributed databases or mobile computing environments is diffcult. Communication disruptions within such systems render the execution of database transactions problematic due to difficulties in atomic commitment strategies. A previously proposed non-traditional system for data and operators, with single site transaction executions and decentralized commitment [9], is useful in specific applications. For this approach, we use some simple analytical and simulation models to assess performance, and provide our findings for straightforward demand-driven and periodic re-allocation strategies.
