This session will get you started with JBoss Business Rules and BPM. It will walk you through some of the capabilities, components and basic concepts that one needs to understand to start building process and rule-driven applications. Join us for an hour of Business Process Management (BPM) concepts, explanations of how to capture your enterprises logic in business rules and a demonstration or two from real live processes that bring these concepts to life. Take a walk with us through several live demos where we explain step by step what is happening and how you too can reproduce these locally. By the end of this session you too can amaze your friends and colleagues, becoming the local JBoss Rules & BPM hero!

12. What is CEP?

13. Example: Multiple Customer Touch Points
Problems:
Hard to derive business relevant
data from available information
Important patterns go undetected
Business fails to respond to
changes in its environment

14. Complex Event Processing
Detect events of significance to a business by recognizing time-based patterns in
one or more real-time data feeds...

21. The Concepts

22. JBoss BRMS
What is inferencing?
●
22
We want to take all of our data (facts) and combine it with our
knowledge (rules) and come up with some conclusions
(inferencing)

27. JBoss BRMS
What is a rule?
●
●
●
●
27
In short, a rule is an premise and conclusion
– If it is raining, then the ground must be wet
A rule is made of conditions and actions. When all the
conditions are met, a rule may “fire”.
The conditions are collectively referred to as the LHS (left
hand side) and the actions are referred to as the RHS (right
hand side, or consequence).
A rule operates on facts (data). In our case, these facts are
instances of objects in our application.

28. JBoss BRMS
Inference Engine
●
●
●
28
The brain of a Production Rule System is an Inference Engine
which matches facts against Production Rules.
When matches are found, the rules actions are fired.
Actions most often change the state of the facts, or perform
some external action on the application.
