Could you tell me about methods of breaking down complex systems into their components?

Methods often used for analyzing complex systems into their components include:

• Functional decomposition: dividing the system into modules or components, each responsible for a specific function.
• Hierarchical approach: identifying levels of abstraction, where the top level describes the overall structure, and lower levels detail the implementation.
• Use of UML diagrams: class, sequence, and component diagrams help visualize structure and interactions.
• Single Responsibility Principle (SRP): each module should have one clear task.

Example: when developing an online store, modules for managing products, orders, users, and payments can be distinguished.
