Meaning
The UML is a complete language that is used to
design, visualize, construct and document
systems. It is largely based on the
object-oriented paradigm and is an essential tool
for developing robust and maintainable software
systems.

3.1 Use Case Diagram
??????????????????????????????? ???????????
???????????????? The use case diagrams describe
system functionality as a set of tasks that the
system must carry out and actors who interact
with the system to complete the tasks.

3.2 Class Diagram
??????????????????????????? The class diagram
is core to object-oriented design. It describes
the types of objects in the system and the static
relationships between them.
18
3.3 Object Diagram
????????????????????????????
19
3.4 Sequence Diagram
???????????????????????? Sequence diagrams
belong to a group of UML diagrams called
Interaction Diagrams. Sequence diagrams describe
how objects interact over the course of time
through an exchange of messages. A single
sequence diagram often represents the flow of
events for a single use case.
20
3.5 Collaboration Diagram
????????????????? ????????????????????????????????
?? Collaboration diagrams belong to a group of
UML diagrams called Interaction Diagrams.
Collaboration diagrams, like Sequence Diagrams,
show how objects interact over the course of
time. However, instead of showing the sequence
of events by the layout on the diagram,
collaboration diagrams show the sequence by
numbering the messages on the diagram. This
makes it easier to show how the objects are
linked together, but harder to see the sequence
at a glance.
21
3.6 State Diagram
????????????????? ???? New, Ready, Running,
Blocked, Halted State diagrams show the dynamic
behaviour of a system. The diagram shows the
various states that an object can get into and
the transitions that occur between the states.
22
3.7 Activity Diagram
???????????????????? (Workflow) Activity
diagrams are a variation of state diagrams which
show the sequence of activity states (states that
are doing something). The diagram can show
conditional and parallel behaviour.
23
3.8 Component Diagram
?????????????????????????????????? ????
?????????????????????????? ????????????????????
Component diagrams show how the physical
components of a system are organized. A component
is a distributable unit of software. The
component diagram allows you to combine
deployment nodes with components to show which
components run on each node (i.e. hardware).
24
3.9 Deployment Diagram
?????????????????????? HW/SW A deployment diagram
serves to model the hardware used in system
implementations, the components deployed on the
hardware, and the associations between those
components.
