I agree that EDA can exist independently of SOA but I don't see EDA as an architecture but more as aspect(s). ... option=com_content&task=view&id=16&Itemid=39...
Daemon, What do you mean by seeing EDA more as an aspect than as an architecture? To my mind, it is a distinct way to organize a system, it has clearly defined...
JJK - Only in some extreme cases would I see EDA as completely covering the system. But note that I said aspect(s) not just aspect recognizing that the...
Joanne, Events are communicated by messages. Context-independence is freedom from concerns surrounding the event's source, a.k.a. autonomy in agent lingo. ...
Here is more on Celtix, Sun et al.: <<Just a few days earlier, the ObjectWeb Consortium had announced a similar open source ESB project called Celtix sponsored...
SOA, to me, is about being able to externalize interfaces and policies and effect invocations over open standards. One of the important contributions of SOA is...
Further comment: <<Ross Mason, a senior developer and member of the Mule project team told ComputerWire: "Personally, I'd like to see us unite further and ...
A question for the debate: Can you design an event-driven system without using the notion of services? Shouldn't the things that process events be services? If...
I tried to make the point that the type of service invocation is not a distinctive factor. In fact, services in SOA should be based on event-triggering...
Yikes. SOA does NOT mandate request/reply style of invocation. That's Gartner speak. Users can invoke Services in an SOA using events just as appropriately as...
... I'd suggest that one of the issues of SOA is to create an optimal architecture for your application. In some cases, open protocols don't add any value....
Ron, I completely agree with you. I think there is a need to differentiate between a Service and "Service Invocation". I look at a Service as a "fundamental...
... In an asynchronous message model such as suggested by the Linda programming model, everyone is a client, except the linda space. In this model, noone is...
Ron, Just to make sure: by request/response I do not refer to synchronous procedure calls. In fact, I think a service invocation should be asynchronous to...

I have just come across an article also relevant to this Group. Read about it at: http://groups.yahoo.com/group/business-process-management/message/130 Gervas...
Gregg, All I said was that SOA requires standard protocols, description languages, and discovery mechanisms. I did not say that those standards must be based...
<<There's a deafening buzz in service-oriented architecture around repositories, which appear to be emerging as a core component of SOA. What is actually...
... Yes, but I wanted to make sure that you were not just talking about WSF. That is the most common meaning associated with any standards speak these days....
... All of the above, although #3 is pretty rare. I don't know very many companies that build new systems from scratch. Most often they extend/modify existing...
Obviously, there's a fair amount of confusion about JBI. Lots of ESB vendors have rallied around JBI, but without the support of IBM and BEA, I have my doubts...
