Julian, sorry to be so long getting back to you -- been travelling. Absolutely what you say is true. The key is simply capturing relational information about...
Hi David, Any thoughts on using an XML database powered by XQuery? It can easily aggregate any kind of content and also federate any database. Do advise... ...
Just to clarify, the characterization David has made of ESP systems might hold for some academic work in stream processing, but it's not true for some...
Ash - XML databases, as well as other forms of DBMS access, must be combined in-line with event stream processing. XML as a DDL/DML, per se, don't change the...
I wanted to re-visit, very briefly, the discussion of ESP and CEP and offer a refinement of these terms. I am searching for a way to reconcile this because...
Hi Ash, as implementations of CEP take off I would expect most of them to use XML representations of events. I am not familiar with XQUERY, sorry to say. But,...
Hi David, Glad to hear from you. I agree that XML will be the de-facto technology in most of the CEP implementations in time. In brief, XQuery is the query...
Mark, good to hear from you! We have an interesting discussion here -- one that I hoped to engender a while ago. We do need standards and checklists for event...
Hi David, Good point regarding the WHAT and HOW... I believe that CEP lends itself well to the heirarchical and flexible nature of XML. XQuery can be used with...
Mark, At first glance: Useful! Thanks for putting the pages together. But your diagram makes ESP look like little more than filtering. ESP creates Derived...
Some useful academic links to add to all of this: http://itlab.uta.edu/sharma/ - Sharma is one of the originators of ECA technology reseach (see HiPAC) ...
Hi, Mark! Nice site, thanks for putting this together for the community. I notice that you left out iSpheres from your line-up of CEP companies. Here is some...
Updated the www.eventstreamprocessing.com. Check it out. 1. Steve - added the links you suggested, good stuff. 2. I think I'll add a larger section on...
To all commercial event processing people out there: Listen up! We need to develop more explanatory examples of event processing, both simple and complex. This...
Steve - can you describe what you envision as the "application use case" for pi-calculus as it might be applied to CEP? - Mark ... science ... record ... On my...
Good question. Causality (which events cause which events) is something that is important to in building distributed event driven applications - regardless of...
Event Stream Processing (ESP) IT Analysis.com Robin Bloor July 21, 2005 I'm adding two new trend predictions here as a consequence of what I've observed in the...
Yes, excellent. But could you flush out pi-calculus from a use case point of view? That is, let's say I have two algorithmic trading system nodes, each...
Steve, the question of how pi-cal relates to CEP crops up quite regularly, particularly in discussions with the BPMS people. pi-calc is a functional language...
David, Wow! Comprehensive response. I shall read carefully. I have only scan read so far. I have been working with Robin Milner for the past 2-3 years and...

Mark, thanks! Good to keep up with these commercial happenings. They are good indications of where the action is going. But ... I can't figure out what...
Sure. Here you go: http://www.timesten.com/ But, before you hurt yourself, we're very familiar with TimesTen and they don't do event processing. They are a...
