Abstract

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 proposed two strategies for caching relevant data items needed during the process of checking integrity constraints of mobile databases. Our strategies analyze the relationships among the integrity tests (simplified form of integrity constraints) to be evaluated for a given update operation. The strategies improve the checking mechanism by not only preventing delays during the process of checking constraints and performing the update but also reducing the amount of data items to be cached. Hence, our strategies speed up the checking process.
