| Summary: | In a mobile environment, due to the various constraints
inherited from limitations of wireless communication
and mobile devices, checking for integrity constraints to
maintain the consistent state of mobile databases is an important issue that needs to be addressed. Hence, in this paper we propose a framework for caching relevant data items
needed during the process of checking integrity constraints
of mobile databases. This is achieved by analyzing the relationships among the integrity tests (simplified form of integrity constraints) to be evaluated for a given update operation. This improves the checking mechanism by preventing delays during the process of checking constraints and performing the update. Hence, our model speeds up the checking process. |
