Functional Architecture Diagram

Functional Architecture Diagram is a graphical tool used to describe the functional components and interactive relationships of a system or software. This kind of diagram usually includes various functional modules, components, interfaces and their interrelationships of the system, as well as the data flow and control flow between functional modules. Functional architecture diagrams can help system designers and development teams clarify the functional composition and structure of the system, and provide a reference for system design and planning. Through the functional architecture diagram, the functional requirements and interactive relationships of the system can be clearly displayed, helping business analysts and requirements engineers to accurately understand user requirements and verify whether the system meets the requirements.
