Synchronization wireless algorithm based on message digest (SWAMD) for mobile device database

Abstract

This research paper presents the design of a proposed synchronization wireless algorithm based on message digest (SWAMD) as an aid to assist data synchronization between the mobile device database and the server-side database. SWAMD proposes storing images from the server-side database and the mobile device database in a message digest table in order to easily compare two images and pinpoint the rows that need to be synchronized. SWAMD makes use of standard SQL functions for the synchronization process. It does not produce timestamps and does not make use of stored procedures nor triggers. The SWAMD techniques are not specific to a particular database vendor.
