The technology rapidly expanding for mobile devices will give a communication capability for mobile users. Every device has its own database so the users can synchronize the data from anywhere and anytime. Recent improvements in mobile device for data synchronization is based on the relational databases and also used an algorithm SAMD (Synchronization Algorithm based on Message Digest) to improve the synchronization. In current practice, mobile application can able to send several requests alternatively to synchronize itself. But relational database involves much more time consuming for data synchronization whenever an application send multiple requests alternatively.
