Introduction

In the computer industry, middleware is a general term for any programming that allows two already existing and separate programs to mediate together.

Middleware architecture is an increasingly familiar topic in enterprise IT. The term middleware is used to define the software that interacts between a network and a database and also in similar situations. Now its term has a border meaning and we can tell it as the very networks that allow the software to run on other devices. Middleware make it easier for the software developers to perform communication and input/output as they can focus on the specific purpose of the application. Middleware is the software layer that is between the applications and the operating system on each side of a distributed computer network.
