Existing and planned system models
Models of the existing system are used during requirements engineering. They help clarify what the existing system does and can be used as a basis for discussing its strengths and weaknesses. These then lead to requirements for the new system. Chapter 5 – System Modeling
Models of the new system are used during requirements engineering to help explain the proposed requirements to other system stakeholders. Engineers use these models to discuss design proposals and to document the system for implementation. Lecture 1
In a model-driven engineering process, it is possible to generate a complete or partial system implementation from the system model.

System perspectives
Context models
An external perspective, where you model the context or environment of the system.
Interaction models
An interaction perspective, where you model the interactions between a system and its environment, or between the components of a system.
Structural models
Behavioral models
Model-driven engineering
A structural perspective, where you model the organization of a system or the structure of the data that is processed by the system.
A behavioral perspective, where you model the dynamic behavior of the system and how it responds to events.

UML diagram types
System modeling is the process of developing abstract models of a system, with each model presenting a different view or perspective of that system.
Activity diagrams, which show the activities involved in a process or in data processing .
Use case diagrams, which show the interactions between a system and its environment.
System modeling has now come to mean representing a system using some kind of graphical notation, which is now almost always based on
