Resilient Extended True-Copy Token Scheme for a Distributed Database System.

A new resiliency scheme for a distributed database system with replicated data is presented. One salient feature of the scheme is that it does not employ a log subsystem; hence, it can be used for a highly reliable system that must tolerate a total crash of a site. In addition, the scheme supports system partitioning without any consistency problem. Tue new scheme is based on a precise treatment of logical data in particular, a precise definition of resilient system operation is given in terms of local data. [ABSTRACT FROM AUTHOR]
