A Heterogeneous Mobile Data Synchronization Technique Using the Tuple Based Message Digest

In mobile database environments, the efficient synchronization technique is required to maintain the consistency of replicated data because the same data can be replicated between so many different databases, In this paper, we propose a message digest based synchronization technique to maintain the consistency of replicated data between client databases and a server database in mobile environments. The proposed data synchronization technique has the advantage of generality aspect and extensibility aspect by using the tuple-based message digest output to detect the data conflicts.
