notes 3. Business Method Integration: One application can share business services provided by the
other applications.
4. Presentation Integration: Provides unified view of data to the end user.
5. B2B Integration: Provides integration of applications residing in two different
organizations.

The best strategy for EAI is Business Method Integration, which allows one application to use
the business services provided by the other applications. It makes B2B integration easier, which
boils down to the choice of technologies for protocol and transport. A protocol defines the
‘language’ for the communication and transport carries the messages as per the protocol from one
application to another. The service oriented Architecture (SOA) acts like an enabler to Business
Method Integration strategy. SOA is the proponent of business driven application architecture,
rather than technology driven application architecture, where a business service can be readily
mapped to a technology component in an application. Embracing SOA along with supports for
multi-protocols (native, SOAP, XML) and multi-transports (TCP/IP, MQ, HTTP) for the service
invocations would truly allow us to implement a flexible and extensible EAI architecture.
6.8 portal-oriented application integration

Portal-oriented Application Integration (POAI) allows us to view a multitude of systems both
internal enterprise systems and external enterprise systems through a single user interface or
application. POAI avoids the back-end integration problem altogether by extending the user
interface of each system to a common user interface most often a web browser (Figure 6.2). As
a result, POAI integrates all participating systems through the browser, although is does not
directly integrate the applications within or between the enterprise.
