Abbreviated as EMS, an
enterprise messaging system
is an enterprise-grade system that enables "program-to-program" messaging
between applications and systems throughout an enterprise. Enterprise
messaging is widely used today for integrating various disparate enterprise
applications. It is a software interface that enables
loosely coupled
asynchronous data (messages) to be
sent by one program and stored in a message queue until the receiving program is
able to process it.
Its important to note that while the term messaging can be used to
describe e-mail, fax, instant messages and other services where humans
read and send the messages, in EMS terminology the word messaging is used
to describe asynchronous messages
that consists of requests, reports or events that are consumed by enterprise
applications and not humans. These messages contain information that is needed
to coordinate systems and track progress of the enterprise.
Enterprise messaging systems, which are language and platform-independent
solutions, are also called messaging services, or more formally, messaging-oriented
middleware (MOM).
