What is generalisation in system analysis and design?

Generalization in system analysis and design refers to the process of identifying common characteristics and behaviors among different entities or components within a system. It allows for the abstraction of these similarities into a higher-level concept or class, thereby simplifying the design and promoting reuse. This technique helps in creating more flexible and maintainable systems by reducing redundancy and enhancing the clarity of relationships within the system architecture. Generalization is commonly used in object-oriented design, where it can lead to the establishment of hierarchies and inheritance.
