Introduction To Rational Rose

• CS 501 Recitation Session
• November 1, 1999

What is Rational Rose?

• ROSE Rational Object Oriented Software
  Engineering
• Rational Rose is a set of visual modeling tools
  for development of object oriented software.
• Rose uses the UML to provide graphical methods
  for non-programmers wanting to model business
  processes as well as programmers modeling
  application logic

3
Why Model?

• Large industrial-strength software systems
  require solid specification. The UML models act
  as an architectural blueprint for software
  development.
• Good models are essential for communication among
  project teams and to assure architectural
  soundness.
• As the complexity of systems increase, so does
  the importance of good modeling techniques.

4
Visual Modeling Tools May Help Mitigate these
Problems

• Software that poorly fits user needs
• Inability to deal with changing requirements
• Software integration problems
• Discovery of serious flaws too late in the
  project
• Software that is hard to maintain and extend

5
When Should ROSE be Used?

• Modeling can be useful at any point in the
  application development process.
• Initial Design Work (Requirement Analysis and
  Definition)
• Use Cases
• Class Diagrams
• Sequence Diagram
• Generality is Good in early design phases. Spend
  your time dealing with issues such as the planned
  uses of software system and how you will
  implement a programming environment to address
  these issues--not where and how you are going to
  place the buttons on your first screen.

6
When Should ROSE be Used?

• Refinement of Early Models (System Software
  Design)
• Introduced in Middle of Project
• Rational Rose includes tools for reverse
  engineering as well as forward engineering of
  classes and component architectures.
• You can gain valuable insights to your actual
  constructed architecture and pinpoint deviations
  from the original design.
• Rose offers a fast way for clients and new
  employees to become familiar with system internals

7
How To Use Rose

• Use Case Diagrams
• Sequence Diagrams
• Class Diagram
• State Diagrams (only on individual Classes)
• Activity Diagrams (only available in 98i versions)

8
HOWTO

• Create New Class, Sequence, or Use Case Diagram
  Right click in browser over Use Case View or
  Logical View and select New Diagram
• Delete Deleting modeling items is very odd in
  Rational Rose
• Diagram Right Click on Diagram name and select
  delete
• Class from Diagram ltDELgt Key
• Class or Message from Model - ltCNTRL-Dgt
• Warning - Rational Rose Does Not Have a powerful
  Undo

9
HOWTO (2)

• Modify properties of Objects
• Double Click on Object in Class Diagram View
• Right Click New Attribute to add
• Right Click and modify properties in Browser
• Attach a File, URL, or note to something to
  describe it better
• Double click on Object to open it
• Tab to Files
• Right click to Insert File
• Add File
