Hi
I read many blogs, one blog says all are same, other says each is diff. I've got some idea on what each of these offers. But pls clarify.

I'm really confused of the terminology that oracle uses for BPEL PM, BPM, BPEL in SOA Suite.

I'm aware of BPEL that comes with the SOA Suite installation, we develop, deploy and maintain BPEL flows using JDev.
Now, what's this BPEL Process Manager, that is listed in the products section, seperately from SOA Suite? Does it contain anything diff from the BPEL engine that is embedded in SOA Suite?

And What's Business Process Management(BPM). As far as i know, and could think of, is that BPM is a tool for modelling business applications. It is similar to the BPEL in SOA Suite PLUS Modelling capability of the business process. It even has the same components as in SOA SUite like BPEL, Business Rules, Human Flows, Mediators, Adaptors.
So, can we say, BPM = SOA Suite + Modelling capabilities of business process.


To summarise, would you please summarise the components that each of these provide

BPEL Process Manager -- BPEL, _(and what other componens)_
SOA SUite -- BPEL, Bus. Rules, Human Flows, Mediators, Adapters
BPM -- Modelling notations, BPEL, Bus. Rules, Human Flows, Mediators, Adapters

If BPEL exists in all the three, Is the engine that runs it also the same one in all three..?
