Middleware is a software that links other software or applications together and allows the passing of data between them. In essence, it is software that sits in the middle of application software and provides an interface between them, even if they work on different operating systems. It allows data found in one database to be accessed in another database. It also allows applications to be free from network services. Middleware was first used to provide a link between old legacy systems and new applications. Today, many companies use middleware as a tool to integrate Enterprise Resource Planning (ERP), Customer Relationship Management (CRM ), and Supply Chain Management (SCM) applications together. Several other reasons why businesses use middleware are to work with suppliers, serve customers, and improve business processes to speed up process time. It can also be used to link business information together from different departments such as finance, research and development, sales, marketing, and so on. Furthermore, middleware can be used to process transactions that take place on the web or computer. Middleware is one component that makes up a Service Oriented Architecture (SOA). Because if it's ability to integrate data from multiple databases and operating systems, middleware software has become a necessity for businesses around the world.
