In the computer industry, middleware is a general term for
any programming that serves to "glue together" or mediate
between two separate and often already existing programs. A
common application of middleware is to allow programs
written for access to a particular database to access other
databases. The systematic tying together of disparate
applications, often through the use of middleware, is known
as enterprise application integration.
Software that mediates between an applications program and
a network. It manages the interaction between disparate
applications across the heterogeneous computing platforms.
The Object Request Broker (ORB), software that manages
communication between objects, is an example of a
Middleware is computer software that connects software
components or applications. The software consists of a set
of enabling services that allow multiple processes running
on one or more machines to interact across a network. This
technology evolved to provide for interoperability in
support of the move to coherent distributed architectures,
which are used most often to support and simplify complex,
distributed applications. It includes web servers,
application servers, and similar tools that support
application development and delivery. Middleware is
especially integral to modern information technology based
on XML, SOAP, Web services, and service-oriented
It sits "in the middle" between application software
working on different operating systems. It is similar to
the middle layer of a three-tier single system
architecture, except that it is stretched across multiple
systems or applications. Examples include database systems,
telecommunications software, transaction monitors, and
The distinction between operating system and middleware
functionality is, to some extent, arbitrary. While core
kernel functionality can only be provided by the operating
system itself, some functionality previously provided by
separately sold middleware is now integrated in operating
systems. A typical example is the TCP/IP stack for
telecommunications, nowadays included in virtually every
In simulation technology, middleware is generally used in
the context of the high level architecture (HLA) that
applies to many distributed simulations. It is a layer of
software that lies between the application code and the run-
time infrastructure. Middleware generally consists of a
library of functions, and enables a number of applications –
simulations or federates in HLA terminology – to page
these functions from the common library rather than re-
create them for each application
