What is Extensibility?
Extensibility is a software engineering and systems design approach in which the software or system is designed to entertain and accept any future expansion implementations. The term is also often used as a measurement of the capacity of a system to introduce additional features and components to its existing structure. Typically, extensions to a system are introduced a new feature or element or through modifying the existing structure and functionality. The primary goal of the extensibility principle is to make the system more compatible with future enhancements and changes while ensuring that these extensions don’t affect the core functions of the system significantly.
Points to Remember
- Extensibility is especially beneficial in a highly fluctuating market. It enables developers to quickly and easily add additional features and capabilities to the software as per the users’ demand and market necessity.
- Extensibility is classified into three types based on the software elements that are changed and how they are changed:
- White-box extensibility
- Gray-box extensibility
- Black-box extensibility
