Meaning – The term middleware, refers to a vague term that refers to the software between an application program and the lower-level platform functions.
Essentially functioning as a hidden translation layer, middleware enables communication and data management for distributed applications. Itis sometimes called plumbing, as it connects two applications together so data and databases can be easily passed between the “pipe.” Using middleware allows users to perform such requests as submitting forms on a web browser or allowing the web server to return dynamic web pages based on a user’s profile.
While all middleware performs communication functions, the type a company chooses to use will depend on what service is being used and what type of information needs to be communicated.
Example of usage – “Common middleware examples include database middleware, application server middleware, message-oriented middleware, web middleware, and transaction-processing monitors.”
