An engine is a type of software that generates source code or markup and produces elements that begin another process, thus allowing the software's requirements to be maintained in real time. In other words, an engine is the self-actualizing element of a complete process, and is therefore the driving motive behind the original process. An engine may also be defined as software that allows for automated processes in which different software elements work interactively to minimize human intervention.
A software engine produces code that is concurrently executed by its originally invoked process. The process is entirely automatic and, unlike some computer programs, it is not managed by daemons or dynamic database triggers. An Internet form component is a perfect example of a software engine. In this case, a user opens a Web browser and completes a form. User-provided input is displayed several pages later. The software engine generates HTML code, ordering the Web browser to schedule the display of these details on a new page. A game engine, or set of programming modules engineered to generate and develop video games, is another example of a software engine. Game engines offer packages of visual development and reusable software elements, which are typically offered in a built-in platform. This enables efficient, data-driven game development.
