Conventional data sharing systems are based on presumption that connections are reliable, and a faulty operation will be considered in case of losing a connection. Flashing connections are characteristic of mobile devices, which lead to the conclusion that networks are not reliable, and the conventional approach might not be the best solution. A possibility to access information in a disconnected situation would certainly improve availability. This paper presents a framework for comparing the quality of important features from a mobile perspective. The availability, reliability and adaptability have been the three main criteria which have been considered for evaluation. The objective is to provide decent availability while sustaining the semantics of information; reliability is thereby important.
