4. UML Diagrams
In the current specification, UML 2, there are two categories of diagrams. Namely 'structure diagrams' and 'behaviour diagrams'.
There are 13 diagram types in all. This mini-web will only cover those you need to know about for this syllabus.
Structure diagrams seek to illustrate the static nature of the system being modelled. They show the architecture of the system and the various objects that make up the overall system.
Structure diagrams include class, object and component diagrams
On the other hand behaviour diagrams try and show how the objects within the system interact with one another.
Behaviour diagrams include activity, sequence and use case diagrams that will be explained later.
This is a class diagram which is explained on the next page
