Sync: a Java framework for mobile collaborative applications

Introducing the factors of wireless mobile systems into the development of collaborative applications complicates developers' lives significantly. Application frameworks targeted for coordinating wireless mobile applications simplify development. The authors describe Sync, a development framework that provides high-level primitives that enable programmers to create arbitrarily complex, synchronized, replicated data objects. Designed for wireless networks, Sync enables applications to share changes at a granularity as small as updates to basic types and so enables better performance on low-bandwidth connections
