Business Process Integration-Oriented Application
Integration (BPIOAI)

BPIOAI

• Integrating applications through their business
  processes is arguably the most important of all
  the service based integration methodologies
• The goal is to create a single logical model
  that spawns across multiple computing
  domains/systems that is linked through services
  and processes

BPIOAI

• BPIOAI is applicable across many types of problem
  domains
• Customer services
• Manufacturing
• Financial transactions
• Human resources

4
BPIOAI

• BPIOAI consists primarily of the following
  elements
• Graphic Modeling Tool used to create the
  business model and define behavior
• Business Process Engine integrates and controls
  the execution of the business processes through
  middleware
• Business Process Monitoring Interface allows
  monitoring and control of the business processes

BPIOAI

• Elements Continued
• Business Process Engine Interface Defines how
  applications will access the process engine
  through the use of integration technology (below)
• Integration Technology a middleware product
  that is used to physically connect the business
  process applications to the engine
• Figure 3.2

Defining BPIOAI

• BPIOAI shares many of the traits of Service
  Oriented Integration (SOI) and Information
  Oriented Integration (IOI)
• In fact, BPIOAI may be used to integrate domains
  that have already been integrated using one of
  the other models
• BPIOAI simply adds another layer of overhead to
  existing integrated systems

An Example

• Lets look at an example from the text building
  a model plane.
• The steps involved include
• Cutting out the parts
• Assembling the parts
• Painting the plane and attaching the decals

8
An Example

• We could further define the build steps in terms
  of processes
• Cut parts
• Assembly Parts
• Finish Plane
• Since were automating/integrating the processes,
  theyll run on a number of differing systems
• Inventory (SAP)
• Sales (Custom)
• Manufacturing (Oracle)

9
An Example

• The process to Cut Parts begins when a sales
  event is generated and posted from the sales
  system to the manufacturing system
• Once the parts have been cut, manufacturing is
  notified that the process is complete, which
  causes it to generate a process to assemble the
  parts
• Manufacturing does the same thing once assembly
  has completed by triggering a message to finish
  the parts

10
An Example

• When finishing is complete, the inventory system
  is updated to reflect the new inventory values
  and the sales system is updated with the finished
  status of the product and the fact that it is
  ready for shipping
• The critical element in this mix is that high
  level processes drive lower level processes and
  facilitate the exchange of information between
  systems

11
Back to BPIOAI

• When integration using BPIOAI, it becomes crucial
  to have a common process model across all systems
  that make up the problem domain
• The model must understand the events that are
  occurring and take into account both success and
  failure states of likely transactions

12
BPIOAI

• A common process model also provides many
  advantages including
• Modeling
• Monitoring
• Optimization
• Abstraction

13
Processes

• When performing integration, processes tend to
  fall into 3 categories
• Internal existing at the corporation level,
  these process are within the organization and not
  visible to those outside the domain
• Shared processes that are used to facilitate
  data exchange between more than one
  corporation/company (visible processes)
• Specialized generally applicable only to the
  interactions between two companies and of limited
  scope
• More examples on pages 66-7

Standards

• BPIOAI is not something that we need to create
  from scratch. Several standards exist to help us
  along in the process
• RosettaNet process oriented standard that
  defines business process flows as Partner
  Interface Processes (PIPs) between trading
  partners
• ebXML Electronic Business Extensible Markup
  Language is a joint venture between the UN Body
  for Trade Facilitation and Electronic Business
  and the Organization for the Advancement of
  Structured Information Standards (OASIS)

  meta language for describing business processes
