Editing Complex event processing (section)

==History==
The CEP area has roots in [[discrete event simulation]], the [[active database]] area and some programming languages. The activity in the industry was preceded by a wave of research projects in the 1990s. According to<ref>{{citation|last=Leavit|first=Neal|title=Complex-Event Processing Poised for Growth|url= http://www.computer.org/csdl/mags/co/2009/04/mco2009040017-abs.html|publisher=Computer, vol. 42, no. 4, pp. 17-20 Washington|date=April 2009}}</ref> the first project that paved the way to a generic CEP language and execution model was the Rapide project in [[Stanford University]], directed by [[David Luckham]]. In parallel there have been two other research projects: Infospheres in [[California Institute of Technology]], directed by [[K. Mani Chandy]], and [[Apama (software)|Apama]] in [[University of Cambridge]] directed by John Bates. The commercial products were dependents of the concepts developed in these and some later research projects. Community efforts started  in a series of event processing symposia organized by the [[Event Processing Technical Society]], and later by the ACM DEBS conference series. One of the community efforts was to produce the event processing manifesto.<ref>{{cite journal|url=http://drops.dagstuhl.de/opus/volltexte/2011/2985|title=10201 Executive Summary and Manifesto – Event Processing|first1=Mani K.|last1=Chandy|first2=Opher|last2=Etzion|first3=Rainer von|last3=Ammon|journal=Drops-Idn/V2/Document/10.4230/Dagsemproc.10201.1 |series=Dagstuhl Seminar Proceedings|editor-first1=K.
