JAX.de 2012 presentation "Business processes, business rules, complex event processing, the JBoss way

1. Business Processes,
Business Rules, Complex
Event Processing with JBoss
Kris Verlaenen – jBPM Project Lead

2. What is a Business Process?
A business process is a process that describes
the order in which a series of steps need to be executed,
using a flow chart.

3. What is a Business Rule?
A principle or regulation governing conduct,
action, procedure, arrangement, etc.

4. What is Complex Event
Processing?
Processing multiple events from an event cloud
with the goal of identifying the meaningful events
within the event cloud.
Event detection
Event correlation
Event abstraction

5. Why?
Visibility Performance
Higher-level Monitoring
Increased agility Speed of development

6. Processes + Rules + Events

7. Motivation
A business solution usually involves the
interaction between these technologies.
Technology overlap
Business overlap
Attribute the same importance to the
three complementary business
modeling techniques

8. Processes Rules Events
Business Logic

13. Vision
A knowledge-oriented platform for
developers and business users

14. Some technical details
for you developers out there !

15. Core Engine
Core engine is an engine in pure Java
workflow + expert system
lightweight
embeddable
Core
generic, extensible Engine

16. Core Engine
Stateful
Knowledge Knowledge
Base Session
Definition Instance

17. Java Interface
startProcess(processId)
signalEvent(type, event)
abortProcessInstance(instanceId)
getProcessInstance(instanceId)
insert(data)
update(data)
remove(data)
fireAllRules()

18. Java Example
// (1) Create knowledge base and add process definition
KnowledgeBuilder kbuilder = ...
kbuilder.add( ..., "sample.bpmn", ResourceType.BPMN2);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
// (2) Create new stateful knowledge session
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
// (3) Start a new process instance
ksession.startProcess(“com.sample.bpmn.hello”);

19. Java Example
// (1) Create knowledge base and add process definition
KnowledgeBuilder kbuilder = ...
kbuilder.add( ..., "sample.drl", ResourceType.DRL);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
// (2) Create new stateful knowledge session
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
// (3) Start a new process instance
ksession.insert(new Person(“krisv“));
ksession.fireAllRules();

20. Java Example
// (1) Create knowledge base and add process definition
KnowledgeBuilder kbuilder = ...
kbuilder.add( ..., "sample.bpmn", ResourceType.BPMN2);
kbuilder.add( ..., "sample.drl", ResourceType.DRL);
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
// (2) Create new stateful knowledge session
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
// (3) Start a new process instance
ksession.insert(new Person(“krisv“));
ksession.startProcess(“com.sample.bpmn.hello”);
ksession.fireAllRules();

21. BPMN 2.0 as the new
standard

22. BPMN 2.0
OMG specification
Model
Notation
Execution semantics
Understandable by business users
Extensible
Interoperability between vendors

24. What we built around that !

30. Ready for the future?
Traditional BPM systems have problems
with change, complexity, flexibility, data-
intensive applications, etc.
Adaptive Case Management (ACM)
Unstructured, non-lineair or flexible processes
Event-driven BPM (edBPM)

31. Combining Processes,
Rules and Events
Integration
From loose coupling
To advanced integration
Unification
Processes and (event) rules are different
types of business knowledge assets
Tooling (IDE, repository, management)
