System Models,agates between devices, and what consistency is maintained. This chapter explores some common alternative models and concludes with the requirements they place on replication protocols. Think of these as choices that one faces when designing a mobile system. In practice, some systems fall squarely i

Partial Replication,ltered) replication supports devices with limited storage and can reduce communication by selectively disseminating items only to the devices where they are needed. The replication protocols and techniques described above ignore issues that arise with partial replicas. These issues include

Case Studies, show how designers have chosen techniques outlined in previous chapters and integrated them into practical systems with varying characteristics. Some of the systems discussed are research prototypes, whereas others are products that are available today. Table 7.1 compares these systems using the fu

Given portable devices with limited resources, weak or intermittent connectivity, and security vulnerabilities, data replication serves to increase availability, reduce communication costs, fost
