Data synchronization in distributed client-server applications

Mobility is one of the major feature in the present computing environment and in the present era of computing almost all the mobile devices have the ability that they can easily be move from one location to other and the data reside on a single system can be utilize via other systems generally using the client-server paradigm . The mobile device can extract needed amount of data from the server and use in both online and as well as in offline mode, but whatever the changes being made during offline work should be copied back to the server and vice-versa whenever the server connects. As the server should always retain most recent data received from client database. So, the data synchronization is a major concern in this scenario by which data confliction can be resolved, data integrity is maintained and most recent data can be placed between the client-server. In this paper the overall data synchronization summary, architecture, tools & techniques between the two devices has been included.
