Modular transformations refer to changes in the structure or function of a system that can be broken down into smaller, interchangeable parts or modules. This concept is often applied in various fields, including software development, engineering, and biological systems, where components can be independently modified or replaced without affecting the entire system. In software development, for example, modular transformations allow developers to update or enhance specific features of an application without rewriting the entire codebase. This approach promotes efficiency, flexibility, and easier maintenance, as each module can be tested and improved individually, leading to more robust and adaptable systems overall.
