Abstract

ARCHITECT: A layered framework for classifying technologies of event-based systems

“…Using regular expressions (such as in [39]) to describe events of interest gives the expressive power of a regular language. In this category we can cite [37], which is the basis of the Snoop system [13], YALES (Yet Another Language for Event Specification) [38], [40], or [41]. EVA (An EVent Algebra Supporting Adaptivity and Collaboration in Event-Based Systems) [42] is a high-level algebra, which allows one to define appropriate operators for applications in many domains.…”

BMQ-Processor: A High-Performance Border-Crossing Event Detection Framework for Large-Scale Monitoring Applications

“…An important feature of such applications lies in situation awareness; the applications continuously monitor and identify if situations or conditions of interest occur. Services are automatically triggered upon the detection of the registered conditions, e.g., an air conditioner is automatically turned on if the temperature of an office is higher than 28 C. Much research on active databases and event-based systems has been performed to support such event detection and task automation [16], [17], [20], [26], [43], [48], [50]. The event detection is done through continuous monitoring of numerous data streams generated from various sensors, GPSs, or agents that are widely deployed throughout physical or virtual (computing) environments.…”

“…Most notably, active databases [8], [17], [18], [24], [43], [51] and event-based systems [5], [13], [20], [26], [27], [50], [55] have evolved for diverse application domains, e.g., logistics, surveillance and facility management, business to business integration, and healthcare. In the course of these efforts, the Event-Condition-Action (ECA) model has been established.…”

“…Starting from active databases, event-based systems (e.g., IRules [5], [50], CompAS [26], [27], Ready [20], Cayuga [13], and SASE [55]) have evolved and been expanded for diverse application domains, e.g., logistics, surveillance and facility management, enterprise applications, and healthcare. An excellent overview on the evolution of active capability toward various event-driven applications can be found in [7].…”

EVA: An event algebra supporting complex event specification

“…The description of composite events requires the definition of operators for event composition. A number of languages have been proposed with different features, e.g., the early language Snoop for active databases [29], CEDL which introduces parameters and aggregates [108], the Amit approach which considers complex events describing situations [5], and SpaTeC which introduces spatio-temporal reasoning [101]. Overviews of event languages have been presented in a tutorial at DEBS 2009 [99] and in a number of publications [68,116,38].…”
