This paper presents the “situation manager”, a tool that includes both a language and an
efficient runtime execution mechanism aimed at reducing the complexity of active …

Active database management systems have been developed for applications needing an
automatic reaction in response to certain events. Events can be simple in nature or complex …

Reaction rules and event processing technologies play a key role in making business and
IT/Internet infrastructures more agile and active. While event processing is concerned with …

An important problem to be addressed within Event-Driven Architecture (EDA) is how to
correctly and efficiently capture and process the event/action-based logic. This paper …

Event-driven reactive functionalities are urgently needed in present-day distributed systems
and dynamic Web-based environments. Reaction rules constitute a promising approach to …

The prediction of future events has great importance in many applications. The prediction is
based on episode rules which are composed of events and two time constraints which …

Misuse Detection systems identify evidence of attacks by searching for patterns of known
attacks (signatures). A main problem in this context is the modeling and specification of …

We propose in this paper an event model supporting duration-based, constrained and
dynamic event types. We believe that many real applications using active DBMS strongly …

Event data analysis is becoming increasingly of interest to academic researchers looking for
patterns in the data. Unlike domain experts working in large companies who have access to …

This paper focuses on the event component of the NAOS (Native Active Object System)
active rule system. It rst gives an overview of the system and then presents the main …
