Definition of a Composite Application

Wikipedia: A Composite Application is an application built by

combining multiple existing functions into a new application.

Extended Definition: Composite Applications are user centric applications supporting highly collaborative and dynamic

business processes which span beyond functional, system,

and organizational boundaries by using data and functions

provided as services by platforms and applications.

Introduction to BPMN

“The primary goal of BPMN is to provide a notation that is readilyund erstandable by al l business users, from the bus iness analysts that

create the init ial drafts of the process es, to the technic al developers

respons ib le for implement ing th e techn ology that wi l l perform thos e

proc esses, and f inal ly, to the business people wh o w i l l manage and

monitor tho se proc esses. Thus, BPMN creates a standardized b r idge for

the gap between the busin ess process design and pro cess

implementation.” OMG, BPMN 1.1 Specif icat ion

!

First published in 2002 Official standard of the Object Management Group (OMG) since 2006

Current Version: BPMN 1.1



Business Process Modeling Notation –

Sequence Flow Overview

Activity

Gateway

Event

Activity: A step in the process

Represents work or action performed

Gateway:

Controlles flow branching, merging and parallel actions

Pure logic – does not do the decision itself

Event: A signal that „something has happened―

Can start, pause and resume or interrupt and

redirect a process or activity



Business Process Modeling Notation -

Activities

Human

Activity

Automated

Activity

Sub-Process

Human Activity:

Activity that has to be processed by a natural Person

Automated Activity:

Activity that is processed by a system

Sub-Process: A compound (decomposable) Activity that holds a

sub-process modeled with BPMN – can be shown

collapsed or expanded




Gateways

Exclusive Choice: Only one path can be taken

Each Gate has a boolean data expression

Parallel Split (also AND gateway):

Splits sequence flow in parallel stream

Event based Choice:

Only one path can be taken

Decision is based on events, not data condition

Uncontrolled Merge:

Merge exclusive alternative incoming sequence

flows to one outgoing sequence flow

Parallel Join:

Merge parallel alternative incoming sequence

flows to one outgoing sequence flow



Business Process Modeling Notation –

Events

Start Event:

Creates new process instance or indicates startof a sub-process

Intermediate Timer Event:

pause the sequence flow of a process

or a sub-process for/until a specific time

Intermediate Message Event: Wait for and receive a message

Intermediate Error:

Aborts activity on error

End Event:

Ends a sequence flow in a process or a sub-process

Termination:

Stop the process or sub-process immediately




Orchestration and Choreography

Pool:

A Pool contains a single „BPMN- Process―

A sequence flow is constrained in exactly one pool A Process diagram may contain several pools

Differentiation between „active― and „inactive― (descriptive) pools

Only one active pool per model

A pool generally represents a logical collection of roles,

organizational units and systems

Lane: A pool may be divided into lanes

A lane generally represents a role or an organizational unit

Orchestration:

Modeling a process flow of control in a single

internal (active) pool

Representation as sequence flow

Choreography:

Modeling interaction between pools (not flow of

control!)

Representation as message flow

Business Rules Overview

© SAP 2007 / Page 26

What are business rules?

Business rules represent the policies, guidelines that drive operational business decisions

Business rules are owned by Business, not by IT

Common Kinds of Business Rules:

Validation Rules Claim Validation, Loan Application Validation

Rate Calculation Rules Computation of Taxes, Interest Rates, Sales Commissions, Premiums,

Bonuses, Duties

Decision Rules Is Applicant Eligible for a Loan Product

Can this good be cleared by Customs?

Recommendation Rules Marketing Promotions, Medical Recommendations, Online Product Chooser

Personalization Rules Website Personalization, Product Personalization , Relationship

Personalization

Internationalization and Localization

Rules

International Products e.g. Maintaining similar Insurance products across

countries

Cross border Custom Duties

Exceptions and Special Rules Exceptions, Special Accounts , Special Arrangements, etc.

Optimization and Configuration Rules Product Configuration, Deal Configuration




SAP NetWeaver

Business Rules Management (BRM)

© SAP 2007 / Page 27

Why Business Rules Management? Externalize business rules from application code Encapsulate rules as re-usable services

Increases flexibility, efficiency and control

Management and monitoring of rules is a critical

component of BPM

Serving business and IT

Why NetWeaver BRM? Robust tool for central business rules management

Integrated path from process to rule

Perfect fit into SAP NetWeaver

Composition Environment

Eclipse based rule composition

Many Ways to Model Rules Model Rules in the Context of a Business

Process using the Process Composer

Model rules as an independent rules project

using the Rules Composer

Many Ways to Integrate Use Rules through an Automated Activity

Model Functions driven by Business Rules

Use rules based mapping transformations in a

process

Use rules based functions for Gateway

Enterprise Services Workplace

The ES Workplace is the central place to view consolidated information of all availableenterprise services delivered by SAP. It provides various entry points for different rolesranging from architect to process experts. ES Workplace is starting point for enterpriseSOA adoption from its discovery of services to the actual testing and building ofexemplary composite applications proofing concept on a freely accessible hostedBusiness Suite for business and technologic justification.

Outside-In

Central design of interfaces that make business sense in SAP NetWeaver

Enterprise Services Repository

Using global data types

Reference to Governance Process

Generation of proxies from abstractly modeled interface

Implementation of ―glue code‖ between proxy and business function

Implementation can be changed without changes in interface

Inside-Out

Start with (existing) implementation in the backend system

Interface semantics pre-defined and reflect directly implementation (virtual

Interfaces allow some view-like mappings)

Process

component

Process components (e.g. Purchase Order Processing, Product

Data Maintenance)

describe a part of the value chain. That part is typically executed by

one department (in large companies).

Process Components are therefore logical groups of business objects.

Deployment units (e.g. ERP)

Are groups of decoupled process components that can be operatedseparately.

<Service Operation>Service operations (e.g. Create Purchase Order, Find Material)

Each belongs to exactly one business object. A business object has

multiple operations.

<Service Interface>Service interfaces (e.g. Manage Purchase Order In, Query

Material In)

Are groups of service operations.

<Business

Object>Business objects (e.g. Purchase Order, Material)

Represent a specific view on well-defined and outlined business

content. Business objects are defined free of business functionality

redundancies.

A business object belongs to exactly one process component.

Is a tool for defining application services, operations (methods) and theassociated business objects that the application service depends on.

Provides a means to implement business logic for the composite application.

Additional features can be automatically provided by the infrastructure such as

document handling, authorization, authentication, logging & tracing.

Supports easy access to external systems via Web Service or RFC models.

Application services can be reused and published as Web Services.
