interfaces, and their relationships.

system and are modeled in the Logical View under the appropriate use-case realization.

participating classes and the relationships among those classes.
It shows all classes whose instances collaborate to perform the use case and their relationships.
It ensures consistency in use-case implementation across subsystem boundaries.

class diagram is made up of the following basic elements
Classes
Relationships
Associations
Aggregations
Generalizations

of objects that share the same attributes, operations, relationships, and semantics.
In the UML, a class is represented by a compartmentalized rectangle.

connection among elements.
A class diagram has three types of relationships
Associations
Aggregate Associations
Generalizations

general relationship and indicates communication only.
In the UML, an association is represented by a solid line with or without an arrow.

a type of association where a whole is related to its part(s).
In the UML, an aggregation is represented by a solid line with or without an arrow on one end and hollow diamond at the end of the aggregate (whole).

diagram can be further defined by
Association Names
Role Names
Multiplicity

a label that clarifies the meaning of the association.
In Rose, the association name is placed along the middle of the association line.

a label that specifies the “face” the class plays in an association.
In Rose, the role name is placed along the association line nearest the class it modifies.

instances a class relates to an instance of another class.
Multiplicity is defined at both ends of the association line.

relationship where one class shares the structure and behavior of one or more classes.
In the UML, a generalization relationship is represented by a solid line with a hollow arrow.

What is an aggregate association?
When should you use role names?
What is multiplicity?
What is a generalization?
