Improving accuracy of context aware data replication in mobile computing application

Published: 14 December 2009 Publication History

Abstract

Mobile applications have made their position clear and proven viable to business operations. Many techniques have been developed to improve performance of mobile computing; one is data replication. This paper explores different data replication problems and proposes a solution to address the context-aware data replication problem, where every single record and entry is tracked and analyzed, while enabling mobile users and main server to exchange data between other and resolve conflicts. The proposed solution makes use of a shadow table, triggers, Remote Data Access (RDA), and a repetition frequency technique to enable the recording of transactional information changes in a data source and reflection of these changes back to the target and vice versa.
While the main advantage of the proposed solution is the increase in accuracy in replicated data, the main disadvantage is the slight increase in processing time caused by the time spent in resolving conflicts between mobile devices. Thus, the proposed solution is better suited for non-real time applications, but where accuracy is central.
