Abstract

We describe a middleware platform for maintaining theconsistency of replicated data called COPla (Common ObjectPlatform). The purpose of replication is to enhance theavailability of data and services in distributed database networks.That is orthogonal to recovery strategies of backed-upsnapshots, logs and other measures to alleviate databasedowntimes. A range of different consistency modes ensuresthe correctness of replicated data.
