introduction

Enterprise Application Integration (EAI) is a process of data and application integration
technologies which focuses on linking transactional applications together, typically in real
time. This differentiates it from EII (Enterprise Information Integration), which is focused on
presenting a unified view of data. It is common knowledge that EII is viewed as a bi-product of
EAI, because, since the application processes are interlinked, the flow of information needs to be
channeled for a unified view. EAI tools are also generally focused on point-to-point application
communications.
Technologies that can make up an EAI solution include web services, transaction monitors,
message brokers, and message queues. Most commonly, EAI vendors discuss messaging and
web services.
In today’s dynamic environment, applications like supply Chain Management, Customer
Relationship Management, Business Intelligence and Integrated Collaboration environments
have become indispensable for any organization that depends upon continuous uninterrupted
production in a solid and competitive commercial environment. And so therefore the EAI
methodologies provide a consistent solution for this. Each of these applications in themselves are
a mamoth effort. Enterprise Application Integration (EAI) is a step forward where it links these
applications and others in order to realize financial and operational competitive advantages.
