System modeling
Objectives
The aim of this chapter is to introduce system models that may be
developed as part of requirements engineering and system design
processes. When you have read the chapter, you will:
■ understand how graphical models can be used to represent
software systems and why several types of model are needed to
fully represent a system;
■ understand the fundamental system modeling perspectives of
context, interaction, structure, and behavior;
■ understand the principal diagram types in the Unified Modeling
Language (UML) and how these diagrams may be used in system
modeling;
■ have been introduced to model-driven engineering, where an
executable system is automatically generated from structural and
behavioral models.
