What Are Classes?
A class is a set of objects that share the
same attributes, operations, relationships,
and semantics.
In the UML, a class is represented by a
compartmentalized rectangle.

Attributes
An attribute defines the characteristics or
structure of a class.
In the UML, a class attribute is displayed in
the middle of the compartmentalized
rectangle.

Operations
An operation is the service provided by the
class. It is the behavior of the class.
In the UML, a class operation is displayed
in the bottom of the compartmentalized
rectangle.

What Are Interaction Diagrams?
An interaction diagram models the dynamic
aspects of the system by showing
relationships among objects and the
messages they may dispatch.
There are two types of interaction diagrams.

What Are Interaction Diagrams?
As with use-case diagrams, you will use
specific input artifacts to create interaction
diagrams.

What Are Interaction Diagrams?
Interaction diagrams are modeled in the
Logical View under the appropriate usecase realization.
They are created based on the use cases
included in the use-case model and the
use-case flow of events.

What Are Sequence Diagrams?
A sequence diagram is an interaction
diagram that emphasizes the time ordering
of messages.

What Are Sequence Diagrams?
A sequence diagram is made up of the
following basic elements
Actors
Objects
Messages
Lifelines
Focus of control

Actors
An actor is someone or something outside
the system that interacts with the system,
either by giving or receiving information or
both.

Objects
An object is an entity with a well-defined
boundary and identity that encapsulates
state and behavior.
An object is an instance of a class.
In UML, the object is represented by a
rectangle with the object name
underlined.

Messages
A message is the communication between
two objects that triggers an event.
In the UML, an object
message is represented
by a labeled arrow in a
sequence diagram.

Lifelines
A lifeline represents the existence of the
object at a particular time.
In the UML, an object symbol is drawn at
the top of the lifeline.

Focus of Control
A focus of control shows the period of time
during which an object is performing an
action, either directly or through a
subordinate procedure.
In the UML, focus of control
is represented by a tall,
thin rectangle.

What Are Collaboration Diagrams?
A collaboration diagram emphasizes the
organization of the objects that participate
in an interaction.

What Are Collaboration Diagrams?
A collaboration diagram is made up of the
following basic elements
Actors
Objects
Links
Messages

Links
A link is a pathway for communication
between objects on a collaboration
diagram.
In the UML, an object link is represented by
a solid line between two objects.

Messages
A message is the communication between
two objects that triggers an event.
In the UML, an object message is
represented by a labeled arrow above the
link in a collaboration diagram.
