Description: The term ‘Non-Intrusive’ refers to a software design and development approach that allows the integration of new functionalities or technologies without requiring modifications to the existing code. This concept is particularly relevant in areas such as software development practices, system architecture, and methodologies that prioritize modularity and adaptability. The main characteristic of a non-intrusive design is its ability to operate independently, minimizing the risk of introducing errors into established systems. This approach promotes modularity and scalability, allowing developers to implement enhancements or new features without affecting the stability of the original system. In general programming practices, non-intrusive design can be achieved through the use of design patterns that encapsulate additional functionality. In summary, non-intrusive design is essential for maintaining software integrity while continuously seeking to innovate and improve.
