Why modeling ?
Better understanding

The advantages of visual modeling
Modeling is a way of thinking about the problems using models organized around the
real world ideas.
• understanding of various interrelationships of a system
• fastest way to delineate the complex relationships
• easier for developers, software architects and customers
to communicate on a common platform

Unified Modeling Language

Why UML ?
• Large enterprise applications
• a way that enables
• Scalability
• security
• robust execution under stressful conditions
• code reuse

RATIONAL ROSE
WHAT WHY AND HOW !!!

•
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.
• facilitates use of the Unified Modeling Language (UML), Component
Object Modeling (COM), Object Modeling Technique (OMT), and
Booch ‘93 method for visual modeling.
History

• 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.
When to use Rational ROSE

• 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

If you want to save a Rational Rose model as a different
format, you may select any of the following options from
the Save As Type list in the
Save Model To dialog box:
• Models *.mdl (the current version of Rose)
• Petal *.ptl
• Rose 6.1/6.5 Model
• Rose 4.5/6.5 Model
• Rose 4.0 Model
• Rose 3.0 Model
If you prefer, you can modify the rose.ini file to always save in a specified format, eliminating
the need to select Save As.
• Difference between the saved model and workspace.
Saving in various format

Extending Rational Rose
• allows you to quickly and accurately customize Rational Rose
environment depending on development needs.
• can install language (for example, Visual Basic, Visual Java, etc.) and
non- language (for example Microsoft Project) tools while in Rational
Rose.
Add-Ins can install:
• Menus (.mnu file)
• Help files (.hlp file)
• Contents tab file (.cnt file)
• Properties (.pty file)
• Executables (.exe)
• Script files (.ebs script source file and .ebx compiled script file)
• OLE servers (.dll file)

•
Capture a Business Process Model.
• Map a Use Case Model to the Business Process Model to define exact
functionality.
• Refine the Use Cases - include requirements, constraints, complexity
rating, notes and scenarios.
• From the inputs and outputs of the Business Process Model and the
details of the use cases, begin to construct a domain model (high level
business objects), sequence diagrams, collaboration diagrams and
user interface models.
• From the domain model, the user interface model and the scenario
diagrams create the Class Model. This is a precise specification of the
objects in the system, their data or attributes and their behaviour or
operations.
How to use Rational ROSE modeling in real life

• As the Class Model develops it may be broken into discrete packages and
components. So from the Class Model a Component Model is built to define
the logical packaging of classes.
• Concurrent with the work you have already done, additional requirements
should have been captured and documented.
• The Deployment model defines the physical architecture of the system.
• Build the system: Take discrete pieces of the model and assign to one or more
developers. In a Use Case driven build this will mean assigning a Use Case to
the development team, having them build the screens, business objects,
database tables, and related components necessary to execute that Use
Case.
• Track defects that emerge in the testing phases against the related model
elements - e.g.. System test defects against Use Cases, Unit Test defects
against classes & etc. Track any changes against the related model elements
to manage 'scope creep'.
• Update and refine the model as work proceeds

How to use Rational ROSE

Use Case Diagrams describe the functionality of a
system and users of the system. These diagrams
contain the following elements:
• Actors, which represent users of a system,
including human users and other systems.
• Use Cases, which represent functionality or
services provided by a system to users.
Use Case Diagram

Class Diagrams describe the static structure of a
system, or how it is structured rather than how it
behaves. These diagrams contain the following
elements.
• Classes, which represent entities with common
characteristics or features. These features include
attributes, operations and associations.
• Associations, which represent relationships that
relate two or more other classes where the
relationships have common characteristics or
features. These attributes and operations.
Class diagrams

Class Specification
•Export Control field.
»Public, private, protected,
implementation
•The Cardinality Concurrency
•A class concurrency defines its semantics
in the presence of multiple threads of
control.

Object Diagrams describe the static structure of a
system at a particular time. Whereas a class model
describes all possible situations, an object model
describes a particular situation. Object diagrams
contain the following elements:
• Objects, which represent particular entities. These
are instances of classes.
• Links, which represent particular relationships
between objects. These are instances of
associations.
Object Diagram

Sequence Diagrams describe interactions among classes. These
interactions are modeled as exchange of messages. These
diagrams focus on classes and the messages they exchange
to accomplish some desired behavior. Sequence diagrams are
a type of interaction diagrams. Sequence diagrams contain
the following elements:
• Class roles, which represent roles that objects may play
within the interaction.
• Lifelines, which represent the existence of an object over a
period of time.
• Activations, which represent the time during which an object
is performing an operation.
• Messages, which represent communication between objects.

Collaboration Diagrams describe interactions among classes and
associations. These interactions are modeled as exchanges of
messages between classes through their associations.
Collaboration diagrams are a type of interaction diagram.
Collaboration diagrams contain the following elements.
• Class roles, which represent roles that objects may play
• Association roles, which represent roles that links may play
• Message flows, which represent messages sent between
objects via links. Links transport or implement the delivery of
the message.
Collaboration Diagrams

Statechart (or state) diagrams describe the states
and responses of a class. Statechart diagrams
describe the behavior of a class in response to
external stimuli. These diagrams contain the
following elements:
• States, which represent the situations during the
life of an object in which it satisfies some
condition, performs some activity, or waits for
some occurrence.
• Transitions, which represent relationships between
the different states of an object.
StateChart Diagrams

Activity diagrams describe the activities of a class. These
diagrams are similar to statechart diagrams and use similar
conventions, but activity diagrams describe the behavior of a
class in response to internal processing rather than external
events as in statechart diagram.
• Swimlanes, which represent responsibilities of one or more
objects for actions within an overall activity; that is, they
divide the activity states into groups and assign these groups
to objects that must perform the activities.
• Action States, which represent atomic, or noninterruptible,
actions of entities or steps in the execution of an algorithm.
• Action flows, which represent relationships between the
different action states of an entity
• Object flows, which represent the utilization of objects by
action states and the influence of action states on objects.
Activity Diagrams

Component diagrams describe the organization of
and dependencies among software implementation
components.
These diagrams contain components, which
represent distributable physical units, including
source code, object code, and executable code.
