EAI (enterprise
application integration) refers to
the plans, methods, and tools aimed at modernizing, consolidating, and
coordinating the computer applications in an enterprise. Typically, an
enterprise has existing legacy applications and databases and wants to continue
to use them while adding or migrating to a new set of applications that exploit
the Internet, e-commerce, extranet, and other new technologies. EAI may involve
developing a new total view of an enterprise's business and its applications,
seeing how existing applications fit into the new model, and then devising ways
to efficiently reuse what already exists while adding new applications and
data. More recently the term "Service Oriented Architecture" or "SOA" has been coined to describe a
system that maps standards-based interfaces to business functions. An SOA
is a common solution to enterprise application
integration challenges.
