The Enterprise Application
Integration (EAI) is clear as the method of accommodating enterprise computer
applications utilizing computer software resources, typically firms have two
type of applications front office and back office applications, to integrate
them in such a means that they can commune with each other when needed either
by simple data passing or by mutual approach of different applications. EAI is
not just about sharing data between applications; it focuses on sharing both
business data and business process. When we talk about EAI it means system of
systems which incorporating large scale inter dependency problems with manifold
heterogeneous distributed systems across a network.
The back office applications are
those associated to the business processes or those applications that are crystal
clear to customer and only the employees or managers have to covenant with for
example Decision Support System (DSS) or an Enterprise Resource Planning (ERP)
and the front office applications are those which are visible to customer or
which are for customer like Customer Relationship Management (CRM), before
integrating these applications we have to be acquainted with about the
communication architectures available, it is contemplation that the best
approach to EAI is to use an Enterprise service bus (ESB), which connects frequent,
independent systems together. Even though other approaches have been explored,
including connecting database level, application layer or user interfaces. In
ESB each independent application just need a connection to the bus so it can circulate
messages and subscribes to receive certain messages from the bus. This approach
can be extremely scalable.
Enterprise Application Integration
is interrelated to middleware technologies such as message oriented
architecture (MOA), data representation Tech. like XML to make the system
highly apparent and scalable, when we talk about scalability web services is
the only technique because everything is coming to web now including web
services like online shopping stores, online banking and even there are some
virtual organizations, universities developing which don't have physical subsistence.
Web Services refuse just appeal to
the technician; however directly address real business needs of today. The
business should care about Web Services, particularly where they directly replicate
some meaningful business concept, and especially where they are being exposed
external - and hence are a manifestation on the business.
The road to organizational
efficiency can often be impeded by measured, dissimilar processes and faulty
communications. Enterprise application integration (EAI) offers the idyllic
solution to addressing these issues. By involving different applications to
simplify and mechanize business procedures, data and business rules can be mutual
across the firm.
Time and again, applications for
example customer relationship management and supply chain management, among
others, are unable to converse with every other, as these are repeatedly
developed using different programming languages and data structures. The solitary
solution is to employ a completely new IT infrastructure designed to contain
integration. This, conversely, is not only expensive, but can also be unruly to
the business as well.
EAI offers an enhanced alternative.
It characteristically utilizes an enterprise service bus to automate business
processes, incorporate diverse business systems, and boost the longevity of
legacy applications. This is through possible through the use of adapters that
have been developed to communicate with unlike software systems utilized in the
firms. The enterprise service bus used must be highly scalable, have the capability
to easily adapt to changes in the organization, and offer a wide range of
integration-focused tools.
Utilizing enterprise application
integration enables you to trounce the workflow challenges that come with
application incompatibility by merging various applications in an enterprise.
It also presents other advantages, such as the abilities to access information
in real-time and maintain data integrity across multiple systems. In addition,
you can eradicate the need for time-consuming and error-prone manual processes,
and have a superior awareness of new contingency. Known all these,
organizational efficiency is veto longer a distant goal with EAI.
