I'll update the entry... On data stream processing I see there is a new book out:- Data Stream Management - <a href="http://www.springer.com/computer/database+management+&+information+retrieval/book/978-3-540-28607-3" rel="nofollow">Data Stream Management - Springer 2009</a> - the authors are from Cornell and Bell Labs. Might be worth a look... An interesting presentation on data stream management and mining (with academic and commercial references) by Georges Hebrail at Ecole Normale Superiuere can be found here: <a href="http://videolectures.net/mmdss07_hebrail_dsmm/" rel="nofollow">here</a> (with <a href="http://videolectures.net/mmdss07_hebrail_dsmm/video/1/slides/" rel="nofollow">slides</a> ). A few other presentations from this <a href="http://videolectures.net/mmdss07_gazzada/" rel="nofollow">NATO conference</a> are worth a look too (... we all know the military have a lot of applications in the CEP domain :) ) Cheers Hi Opher - good catch! I’ll update the entry…

Just a comment on your endnote [1] -- while both active database and data steam management came from the database research community, there were actually two different paradigms. Active databases advocated embedding rules in a database engine, while data stream management advocated the processing of streams of events in time windows against queries. Each approach has its own benefits and shortcomings, and each of them have descendents in the product space of event processing that we see today. cheers, Opher Hi Paul.
