System Modeling: Chapter 5

System modeling is the process of developing abstract models of a system, presenting different views or perspectives. It is typically represented using a graphical notation, often based on the Unified Modeling Language (UML).

Models of the existing system are used to clarify what the system does, and to discuss its strengths and weaknesses, leading to requirements for the new system.

Models of the new system are used to explain proposed requirements to stakeholders, discuss design proposals, and document the system for implementation.
