Subject: Re: [soa-rm-ra] random question
While I agree completely that data is *always* involved in services, I do not think that that is the key aspect of SOA. I would assert that *action* is of the essence in SOA, not *data*. Contrast this with the normal Web architecture. In that model, information is of the essence, and action is a side-effect.
