Abstract

In this work we address the problem of managing the reactive behavior in distributed environments in which data continuously changes over time, where the users may need to explicitly express how the triggers should be (self) modified. To enable this we propose the (ECA)2Evolving and Context-Aware Event-Condition-Action paradigm for specifying triggers that capture the desired reactive behavior in databases which manage distributed and continuously changing data. Since both the monitored event and the condition part of the trigger may be continuous in nature, we introduce the concept of metatriggers to coordinate the detection of events and the evaluation of conditions.
