What perspectives should be used for developing models of a software
system?
An external perspective should be used where you model the context or
environment of the system.
You should also have an interaction perspective, where you model the
interactions between a system and its environment, or between the
components of a system.
It is also keen to have a structural perspective, where you model the
organization of a system or the structure of the data that is processed by
the system.
Last but not least, a behavioral perspective, where you model the dynamic
behavior of the system and how it responds to events.
What UML diagram types do you need to represent the essential features
of a system?
Activity diagrams, Use case diagrams, Sequence diagrams, Class
diagrams, and State diagrams are all essential features of a system.
Activity diagrams show the activities involved in a process.
Use case show the interactions between a system and its environment.
Sequence diagrams show interactions between actors and the system and
between system components.
Class diagrams show the object classes in the system and the associations
between other classes.
State diagrams show how the system reacts to internal and external
events.
What is described in a context model?
