BASIC VIEWS

UML views a system in five different viewsıuse case, structural, behavioral, implementation, and environmental (see Figure 1).

Figure 1ıThese are modeling views of a system (UML perspective).

Also, UML provides many diagrams to view a system. All the diagrams can be classified according to the above views (see Table 1).

View	Used for	Diagram(s)
Use case	Functional requirements	Use case
Environmental	Physical constraints	Deployment
Behavioral	Design refinement	Sequence, collaboration, activity
Structural	Design refinement	Domain, class, package
Implementation	Low-level design	Component, state
Table 1ıDifferent views of a system are designed to aid in various stages of the development work, and each view of a system is best represented by certain diagrams.
