Right now I am writing my thesis about Oracle Complex Event Processing and Oracle BAM in the context of the open source enterprise service bus of SOPERA and orchestrated services through Oracle BPEL. I was struggeling in understanding the difference between an event cloud and an event stream. This article gave me a good understanding, of the difference between both. But I have still a problem in understanding CEP in this context. I got it, that CEP contains a subset of streams, but how can CEP act without having a certain time frame? Do I need unlimeted memory to cache all my events for correlation purpose? I am a student within the CITT comming from the university of applied sciences regensburg.
