EAI Concepts
Definition 1
 Another name is EII (Enterprise Information Integration), BPI (Business
Process Integration)
 BPI: Business Process Integration, or EAI, is a software solution that allows
businesses to integrate internal applications, securely connect with business
partners over the Internet, and automate business processes.
 EAI (enterprise application integration) is a business computing term
for the plans, methods, and tools aimed at modernizing, consolidating,
and coordinating the computer applications in an enterprise.
 Integrates applications and enterprise data sources so that they can easily
share business processes and data. Integration is done without significant
changes of applications and data sources [http://girtab.ucc.ie/]

Definition 2
 Enterprise application integration (EAI) is a new label for an
old problem, namely that of integrating business systems in
order to let them share resources such as data or processes.
The severity of this problem becomes more and more
apparent with the increasingly complex information systems
of modern organisations

 Information Sharing – EAI enables the flow of
information between separate software programs within a
company, as well as from outside the company’s own
computer systems. EAI can consolidate data collection
efforts, eliminating the redundancies of having each
application collect and store data for its own purposes.
Integration also creates a single point of access to data for the
people who need it. That means employees spend less time
searching for information – and the data they get is often
more complete and up to date. EAI also enables more
effective collaboration between individual people and
departments.

 Process Automation – EAI can streamline processes that
include data or activity from multiple software applications.
For example, data from a CRM can be integrated with an email marketing platform to deliver targeted messages to
customers based on their prior behavior or demographics.
That effort could then be coupled with an analytics package
to measure the success of the email campaign. And all that
data can be integrated with an ERP system to help the
company invest resources where they’re most effective.

 Reduced IT Complexity – Most enterprise-level
companies find it difficult to use new technology effectively.
The learning curve is often steep, and a new application may
not work well with the systems already in place. Enterprise
application integration overcomes these roadblocks to
smooth business process by combining the information and
functionality of several applications into a single, easy-to-use
interface.

 Increased Agility – One of the highest business benefits of
enterprise application integration is that it allows
organizations to recognize and respond to opportunities
more quickly. EAI can help companies address shifts in the
market, reputation management issues, supply chain
disruptions and more – all from a single interface.
