What is CEP?
13
Problems:
Hard to derive business relevant data from available information
Important patterns go undetected
Business fails to respond to changes in its environment
Example: Multiple Customer Touch Points
14
Complex Event Processing
Detect events of significance to a business by recognizing time-based patterns in one or more real-time data feeds...
“Weather delay in London”
Business Rules

What is a BPMS?

A Business Process
Catalog
Orders
Shipping
Financials
Inventory
Packaged Apps (e.g. SAP)
An activity or set of activities that will accomplish a specific organizational goal...

JBoss BRMSWhat is inferencing?
● 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 BRMSWhat is a rule?
● 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 BRMSInference Engine
● 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.
