Business Processes, Business Rules, Complex Event Processing with JBoss

Kris Verlaenen jBPM Project Lead

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.

What is a Business Rule?

A principle or regulation governing conduct, action, procedure, arrangement, etc.

What is Complex Event Processing?

Event detection

Event correlation

Event abstraction

Processing multiple events from an event cloud with the goal of identifying the meaningful events within the event cloud.

Why?

Visibility

Higher-level

Increased agility

Performance

Monitoring

Speed of development

Processes + Rules + Events

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

Business Logic

Events

Processes

Rules

Vision

A knowledge-oriented platform for
developers and business users

Some technical detailsfor you developers out there !

Core Engine

Core engine is an engine in pure Java

workflow + expert system

lightweight

embeddable

generic, extensible

Java Example

// (1) Create knowledge base and add process definitionKnowledgeBuilder kbuilder = ...kbuilder.add( ..., "sample.bpmn", ResourceType.BPMN2);

KnowledgeBase kbase = kbuilder.newKnowledgeBase();// (2) Create new stateful knowledge sessionStatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();// (3) Start a new process instance

ksession.startProcess(com.sample.bpmn.hello);

Java Example

// (1) Create knowledge base and add process definitionKnowledgeBuilder kbuilder = ...

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)

Combining Processes,
Rules and Events

IntegrationFrom loose coupling

To advanced integration

UnificationProcesses and (event) rules are different types of business knowledge assets

Tooling (IDE, repository, management)

Enterprise versions provide long-term support, regular releases including fixes, new features, and new platforms certifications.

New community features may be backported to Enterprise versions

JBoss Enterprise Product Delivery ModelExample: jBPM Community and Enterprise Product

While community projects continue to rapidly evolve,
enterprise middleware products focus on long term stability.
