Rational Rose provides support for two essential elements of modern software engineering
Component based development
Controlled iterative development
Rational Rose use
Component Object Modeling (COM)

4. Introduction to Visual Modeling Using a Rational Rose (cont’d)
Help organize, visualize, understand, and create complex things
The mapping of real world processes of a system to a graphical representation.
Useful for understanding problems, communication with everyone involved with the project (customers, domain experts, analysts, designers, etc.), modeling complex systems, preparing documentation, and designing programs and databases.

Modeling promotes better understanding of requirements, cleaner designs, and more maintainable systems
Visual modeling captures business processes by defining the software system requirements from the user’s perspective

Modeling with Rational Rose
Rational Rose is the visual modeling software solution that lets you create, analyze, design, view, modify and manipulate components and implement system in a way that makes them truly easy to communicate

Describe model elements or relationship
The description can include such information as the roles, keys, constraints, purpose, and essential behavior of the element

Diagram Window
Diagram windows allow you to create and modify graphical views of the current model
Each icon in a diagram represents an element in the model

Specification Window
A specification enables you to display and modify the properties and relationships of a model element, such as a class, a relationship, an operation, or an activity

12. Introduction to Diagrams
Overview
Diagrams are views of the information contained in a model
Diagram windows
Class diagram
Use-case diagram
Collaboration diagram
Sequence diagram

13. Introduction to Specifications
A specification enables you to display and modify the properties and relationships of a model element, such as a class, a relationship, or an operation
Kyung Hee University

14. Class Diagrams and Specifications
Class diagram overview
A class diagram is a picture for describing generic descriptions of possible systems
Class diagrams and collaboration diagrams are alternate representations of object models
Class diagrams contain classes and object diagrams contain objects, but it is possible to mix classes and objects when dealing with various kinds of metadata, so the separation is not rigid
Kyung Hee University

15. Class Diagrams and Specifications (cont’d)
Class specification
A class specification displays and modifies class properties and relationships
Stereotype
A stereotype represents the subclassification of an element
It represents a class within the UML metamodel itself
Some stereotypes are already predefined, but you can also define your own to add new kinds of modeling types
Kyung Hee University

16. Class Diagrams and Specifications (cont’d)
Cardinality
The cardinality field specifies the number of expected instances of the class.
In the case of relationships, this field indicates the number of links between each instance of the client class and the instance of the supplier
You can set a specific cardinality value for the client class, supplier class, or both

Specified range of instance
<literal>..<literal>,<literal>
The number of instances will be in the
Specified range or an exact number of
instances
<literal>..<literal>,
The number of instances will be in one of the specified ranges

18. Class Diagrams and Specifications (cont’d)
Concurrency
A class concurrency defines its semantics in the presence of multiple threads of control
Kyung Hee University

19. Class Diagrams and Specifications (cont’d)
Type
Description
Sequential (default)
The semantics of the operation are guaranteed only in the presence of a single thread of control. Only on thread of control can be executing in the method at any one time
Guarded
The semantics of the operation are guaranteed in the presence of multiple threads of control. A guarded class requires collaboration among client threads to achieve mutual exclusion
Active
The class has its own thread of control
Synchronous
The semantics of the operation are guaranteed in the presence of multiple threads of control; mutual exclusion is supplied by the class
