摘要

The well-developed traditional data management techniques need to be augmented with new approaches in order to continue to be effective in the mobile environment. In this paper, we focus on the challenge of maintaining integrity constraints in the presence of disconnections and expensive communication. Our approach of localization is to reformulate global constraints so as to enhance the autonomy of the mobile hosts in processing transactions. We show how this approach unifies techniques of maintaining replicated data with methods of enforcing polynomial inequalities. We also discuss how localization can be realized in PRO-MOTION, a flexible infrastructure for transaction processing in a mobile environment.
