Resumen de Blocking and non blocking reliability protocols in distributed database systems
August Climent i Ferrer, Josep Maria Muixi
Lately database systems have been evolving into distributed databases, in order to increase their performance. We assume a distributed database as the software system that permits the management of local databases maintaning the network transparency of the system. There are two very important topics in a distributed database system: Reliability and Avaialbility. Availability is the probability that the system does not experience any failures in an interval of time. In this paper we present the different reliability protocols used in distributed database systems. In these systems, it is useful to study the behavior of the system when faced wirth site failures and the recovery protocols used.
