notes 6.10 portals and application integration

Portals are nothing new, we’ve been building them since the web took off and we first understood
the value of externalizing existing enterprise data through web interfaces. That was the birth of
B2C e-Business, which led the way to B2B e-Business which is after all what POAI is all about.
What is new is the reliance of POAI to support huge transactions and to support enterprises that
no longer have to pick up the phone or send a fax to buy, sell, or trade. POAI removes the need
for human interaction to support a business transaction. The only requirement is an interaction
with a web browser.
Unfortunately, although they are a necessity today, portals do not support the ultimate goal of
application integration the exchange of business information in real time in support of business
events that do not require human interaction. The goals of application integration are to design
the user out of the process, thus removing the greatest source of latency in the exchange of
information and to support the new event-driven economy.

6.11 portal-oriented B2B application integration

Portal-oriented B2B application integration allows us to view a multitude of systems both internal
enterprise systems and external, trading community systems through a single user interface
or application. Portal-oriented B2B application integration benefits us through avoiding the
back-end integration problem altogether; it extends the user interface of each system to a common
user interface (aggregated user interface), most often a Web browser. As a result, it integrates all
participating systems through the browser, although the applications are not directly integrated
within or between the enterprises.
Portals have become so common, and so much has been written about them that we will cover
just the basic concepts here. The important point to remember in the context of B2B application
integration is that portals have become the primary mechanism by which B2B application
integration is being accomplished. Whether that is good, bad, or indifferent doesn’t really matter.
This is simply the way it is. The reach of internal enterprise systems has been extended to trading
partners by utilizing the familiar Web browser interface.

Task Check near by you and choose a small business owner apply POAI on that
business.

6.12 research in source integration

EAI is considered strategic because its potential contribution is measured in terms of attaining
or exceeding key performance and competitive benchmarks for entire industries, as noted in the
following examples.

Banking

The basis of competition in banking and financial services is customer retention. Customers
with multiple accounts are less likely to change, but most financial institutions have stovepipe
systems for credit cards, checking, savings, mortgage, brokerage, and other services. An EAI
implementation would integrate the systems so that a data warehouse can aggregate account data,
provide a single view to the customer, and recommend what additional products the customer
should be offered. In EAI systems instituted at Bank of America (Bank of America (NYSE: BAC
TYO: 8648 ) is the largest commercial bank in the United States in terms of deposits, and the
