Solving Problems in Software Applications through Data Synchronization in Case of Absence of the Network

In this paper, we have presented an algorithm for data synchronization based on Web Services (WS), which allows software applications to work well on both configurations Online and "Offline", in the absence of the network. For this purpose is in use Electronic Student Management System (ESMS) at University of Prishtina (UP) with the appropriate module. Since the use of ESMS, because of a uncertain supply of electricity, disconnecting the network and for other reasons which are not under the control of professional staff that manages the performance of this system, has interruption to the online work. In order to continue work in such conditions, are founded adequate solutions to work in offline mode and later data synchronization in normal conditions.
