Quick overview of BPMN building blocks

BPMN consists of three main objects: Activity: Represents work to be done

Gateway: Controls flow logic of the process. Used for splitting and merging paths. Event: Supports asynchronous communication with other processes, error handling,

and controlling flow logic

Activity Gateway Event

Sequence Flow BPMN connection object

A Sequence Flow is used to show the order that activities will be performed in a Process.

Embedded Sub Process

Embedded Sub Process

Used for simplified representation of Processes.

It is also used to set the scope of event handling.

Provide better process

modularization andencapsulation

Provide better reusability

Promotes multi-ownership of different parts of

the process.

Using Events To Instantiate A Process

Listens to external signals and creates anew process instance.

Common Types of Start Events.

None Called from a Main process.Sub-processes must always start withNone Start Event.

Message Triggered by the arrival ofa Message.

Timer Triggered based on someschedule.

Signal Triggered based on thearrival of a subscribed signal viabroadcast mechanisms. The senderis unknown in this case and the

Signal Start Event listens on a wellknown topic.


14/3314

Multiple End Events

Process completes only when all Paths are completed.

Common Types of End Events

o None Normal Completion. The control passes to the subsequent step in the main process if asubprocess completes normally.

o Message Sends a Message before Completion.

o Signal Broadcasts (publishes) signal before Completion.

o Error Throws Error Before Completion.

o Terminate Process ends abruptly.

Exposing Process As A Service

The Process then

becomes a ServiceProvider and can beinvoked by otherBPMN or BPELprocesses.

The Message StartEvent andcorrespondingMessage End Eventtransforms in to endpoints ( Operations).

Unified Services across BPM & SOA

2009 Oracle Corporation Proprietary and Confidential BPM Methodology Workshop Rev 3.0

Shared SOA Services - Oracle BPM 11g is based of a unified architecture andshares the same set of Task Services, Decision (Rule-based) Services, AdapterServices with the Oracle SOA 11g product.

Zero-code IT Environment - BPM Studio is unified with JDeveloper and SOA toolingproviding IT users the same set of zero-code capabilities, including adapters, events,transformations, rules, etc.

Summary

What you model is what you execute

Keep models simple process decomposition is key

Use embedded sub-processes

Reusable sub-processes

Make judicious use of event sub processes to Process models should reflect business flow

Delegate technical logic to SOA components

Leverage SCA components and Adapter framework

Encapsulate workflow routing logic in Human Task definitions

Externalize business logic wherever possible to Oracle BusinessRules Engine
