Describe how middleware is used.
What will be an ideal response?
To access data in a web-based system, the database must be connected to the Internet or intranet. The database and the Internet speak two different languages, however. Databases are created and managed by using various languages and commands that have nothing to do with HTML, which is the language of the web. The objective is to connect the database to the web and enable data to be viewed and updated.To bridge the gap, it is necessary to use middleware, which is a software that integrates different applications and allows them to exchange data. Middleware can interpret client requests in HTML form and translate the requests into commands that the database can execute. When the database responds to the commands, middleware translates the results into HTML pages that can be displayed by the user’s browser.
