This paper proposes a Stateful Synchronization of data between a server-side database and a mobile database. The Stateful Synchronization stage is an amalgamation of the Stateful and Synchronization modes. This means that invalidation reports are sent only to the affected clients (Stateful) and they are sent periodically (Synchronous).The existing Synchronization Algorithms based on comparison of message digest values of the selected rows of both server-side database and mobile database needed for Synchronization. But in the proposed approach the server keeps the information of the present state of data records at the mobile databases.
