Ok, you have a "scenario" (in what format is a scenario?).
You then want to build a web service, that can exploit this scenario.
But I'm not sure how DI Studio fit into this picture. Do you want the "CBS" application to call a DI Studio job that calls a web service?
DI Studio can be part of streaming and near real time set-ups, but with the little knowledge I have on this particular situation, I doesn't sounds lie a DI Studio application.
Can't you call the web service directly from CBS?
