Interesting times here at TIBCO and beyond. In fact, it seems like according to the zeitgeist, it's one of those tumultuous times where everyone is constantly reminded of pending change.
There's also change of some sort in the political environment coming here in the U.S. I'm not going to take any political stands in this blog, but if you're familiar with Greg Reemler aka “Greg the Architect” and the folks at Techrotech, they're also contemplating change too. This one was too good for me not to share.
Lots of reasons for us all to re-evaluate how we cope with change… and CEP interestingly enough can help companies do just that. Recently, we concluded our event processing Online Summit and had the author, blogger and enterprise decision management proponent James Taylor as one of the keynote presenters. We had over 900 attendees listen and ask questions — many of which were along this line — What is the relationship and difference between CEP and BI (real-time and operational BI)?
The most noticeable difference is the event driven, real-time nature of CEP versus the query driven approach of traditional BI tools. CEP, at least in terms of TIBCO's approach, is declarative which means the presence (or absence) of an event can determine how the business rules fire and ultimately how the system responds to the detected situation. In other words, BI makes you ask questions in order to get an answer and CEP gives you an answer based on real detected events.
CEP could utilize BI or analytics as a source of events or source of rules. You might be able to use BI to query a database to determine rules, but you would be better off applying the rules in real time in a CEP system to take advantage of CEP's real time nature. This means you can detect fraud when it happens — not after it's too late.
It's a fundamental difference that event processing is based on data in motion versus the static “data at rest” in a database. CEP systems can usually detect more event sources and types than traditional BI which relies on a database. That’s the old way of doing things. CEP is also much better at finding out root cause and why something happened: users can drill down from a complex event to find what source events led to that situation (or complex event).
So that's my story and I'll stick with it. To those of you dealing with some sort of change, breathe in and hang in there. To those of you in the US, happy election - and make sure to get out and vote, even if it’s for Paris!
