title = "Triggers and continuous queries in moving objects databases",
abstract = "This work addresses the problem of maintaining the consistency of the answers to continuous queries which are posed by the users of the Moving Objects Databases (MOD). We propose a framework which enables detecting and processing the pending queries whose answers need to be re-evaluated upon modifications to the MOD. Relevant syntactic elements of the user's queries and their semantic implications are identified, and the basic components of a system that can be used for this task are specified. We show how triggers can be used to maintain the answers to the users' queries {"}up to date{"} with respect to the modifications to the MOD and we demonstrate that our system can be implemented on top of the existing ORDBMS.",
