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.
Operations
Responsibilities

How Are Classes Found?
Classes can be discovered using various artifacts.

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.
Sequence
Collaboration

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

Interaction Diagrams

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

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
What Are Sequence Diagrams?

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.
Message

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.
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.

Show Unresolved Objects
The Show Unresolved Objects report lists all unresolved objects in a collaboration or sequence diagram.

Show Unresolved Messages
The Show Unresolved Messages report lists all unresolved messages in a collaboration or sequence diagram.
