In this work we address the problem of managing the evolution of different context dimensions in context-aware pervasive environments. We postulate that, in addition to the correlation of different observed/measured values from different sensors, the reaction to a particular event may need to have proactive consequences, in the sense of focusing on monitoring activities in different locations, that previously were of no interest. Towards that end, we argue that a modification of the triggers used in the Active Databases, may provide a paradigm that caters the desired awareness.
