Which methodology is basedon the notation of functions;programs consist of modules to meet functional requirements?

The Structured Approach is a methodology that is based on the notation of functions; programs consist of modules to meet functional requirements. The Structured Approach focuses on the processes involved in a software system, modeling them as a series of connected steps. It follows a top-down approach, breaking down complex systems into smaller, simpler parts that can be more easily understood. It also focuses on the data that a software system manipulates, modeling it as data flows between processes. It emphasizes the functional decomposition of a software system into smaller, independent functions12. References: 1: Difference between Structured and Object-Oriented Analysis12: Traditional vs. Object-Oriented Approaches: Object-Oriented Approach: Analysis2
