Abstract
1 Introduction Event-based communication has become a new paradigm for building large-scaledistributed systems. It has the advantages of loosely coupling communication partners, being extremely scalable, and providing a simple application program-ming model. In event-based systems, events are the basic communication mechanism. An event can be seen as a notification that something of interest hasoccurred within the system. Components either act as event sources and publish new events, or event sinks and subscribe to events by providing a specificationof events that are of interest to them. A publish/subscribe (pub/sub) communication layer [1] is then responsible for disseminating events; for efficiency, it canoften also filter events by topic or content, according to client specifications.

This paper factors out the common denominator underlying these variants: full decoupling of the communicating entities in time, space, and synchronization to better identify commonalities and divergences with traditional interaction paradigms.
Storing and querying ordered XML using a relational database system
2,248 Citations2002Igor Tatarinov, Stratis D. Viglas +4 more
This paper shows that XML's ordered data model can indeed be efficiently supported by a relational database system, and proposes three order encoding methods that can be used to represent XML order in the relational data model, and also proposes algorithms for translating ordered XPath expressions into SQL using these encoding methods.

Hermes: a distributed event-based middleware architecture
481 Citations2003Peter Pietzuch, Jean Bacon
Her Hermes, a novel event-based distributed middleware architecture that follows a type- and attribute-based publish/subscribe model that centres around the notion of an event type and supports features commonly known from object-oriented languages like type hierarchies and super-type subscriptions is introduced.
Data & Knowledge EngineeringSnoop: An expressive event specification language for active databases
472 Citations1994Sharma Chakravarthy, Deepti Mishra
The novel aspect of this work lies not only in supporting a rich set of events and event expressions, but also in the notion of parameter contexts, which augment the semantics of composite events for computing their parameters.

Event specification in an active object-oriented database
248 Citations1992Narain Gehani, H. V. Jagadish +1 more
A new Event-Action model is proposed, which folds into the event specification the condition part of the well-known Event-Condition- action model and avoids the multiple coupling modes between the event, condition, and action trigger components.
Detecting composite events in active database systems using Petri nets
241 Citations2002Stella Gatziu, Klaus R. Dittrich
It is demonstrated how Petri nets can be used as the basis of a mechanism suitable to model the semantics of composite events and to implement the event detector in the context of the SAMOS active database system prototype.

The paper discusses the effect of communication delays on composite event detection and presents a tree-based solution for dealing with out-of-order event arrivals at event monitors.

Algorithms for event composition and event consumption are presented which make use of accuracy interval based timestamping and illustrate the problems that arise due to inaccuracy and message transmission delays.
Information flow based event distribution middleware

This work presents a flexible new model, the Information Flow Graph (IFG), for specifying the flow of information in event distribution middleware and illustrates the use of the IFG for content-based publish/subscribe; stateless event transformations that consolidate events from diverse sources; and stateful event interpretation functions for deriving trends, summaries, and alarms from published events.
Monitoring the behaviour of distributed systems
42 Citations2021Scarlet Schwiderski
This dissertation is concerned with monitoring the behaviour of distributed systems in terms of physical time, i.e. the syntax, the semantics, the detection, and the implementation of events, and algorithms for the detection of composite events are developed.
