STUDY OF CASE TOOLS

VISUAL MODELLING:

Visual modeling is a way of thinking and analyzing about problemsusing models around real world ideas. A modeling language must include,

Model elements

Notations

GuidelinesVisual modeling approach is used since a system cannot be

comprehended to its entirety. Benefits of visual modeling includes,

Clarity

Familiarity

Maintenance

simplification

UML:

Unified modeling language(UML)is a communication standard of visualmodeling. The UML provides a smooth transition between the businessdomain and the computer domain. UML is an object oriented language forspecifying, constructing, visualizing and documenting the software systemand its components.UML is a graphical language with a set of rules and semantics.UML is a combination of

Data Modeling

Business Modeling

Object Modeling

Component Modeling

UML DIAGRAMS:UML defines graphical diagrams such as,

Class diagram

Use case diagram

Behavior diagrams

Interaction Diagramso Sequence Diagramso Collaboration Diagrams

State Chart Diagrams

Activity Diagram

Implementation Diagramso Component Diagram

o Deployment Diagrams

USE-CASE DIAGRAMS:Use-case diagrams graphically depict system behavior (use cases).Thesediagrams present a high level view of how the system is used as viewed froman outsiders (actors) perspective. A use-case diagram may depict all orsome of the use cases of a system.A use-case diagram can contain:

Actors (things outside the system) Use cases(system boundaries identifying what the system should do)

Interactions or relationships between actors and use cases in thesystem including the associations, dependencies and generalizations.

USE CASE: Use case is scenario for understanding system requirements. Everysingle use case must describe one main flow of events.

ACTOR

Actors represent system users, who provide input to and receive

information from the system. An actor is a stereotype of a class and isdepicted as a stickman on a use-case diagram. The name of the actor isdisplayed below the icon. Additional information about the actor can beviewed in the use-case specification.RELATIONSHIPS

You can add relationships to the diagram to show interactions betweenactors and use cases. Association relationships can be drawn from an actorto a use case. The generalize relationship can be drawn between actors.

Relationships between use case diagrams include

Communication

Uses Extend

FLOW OF EVENTSA flow of events is a sequence of transaction (or events)

performed by the system. They typically contain very detailed information,written in terms of what the system should do, not how accomplish the task.A flow of events should include:

When and how the use case starts and ends

Use case/actor interactions

Data needed by the use case

Normal sequence of events for the use case

Alternate or exception flowsUSE-CASE REALIZATIONS (SCENARIOS)

A use case realization is a graphic sequence of events, also referred toas a scenario or an instance of a use case. these realization or scenarios aredepicted in either a sequence or collaboration diagram.

The two most common scenarios are the typical(or primary)scenario,where all is well and the exception(secondary)scenario, which address thedeviations. The exception scenario address the what if ? elements of theuse case.

ACTIVITY DIAGRAM:An activity represents the performance of task or duty in a workflow. it

may also represent the execution of a statement in a procedure. An activitydiagram is activity centric. Transitions connect activities with other model

elements and object flows connect activities with objects.The activity icon appears as a rectangle with rounded ends with name

(take order and process order) and a compartment for actions.The name of an activity must be unique and should declare the

activitys purpose. All activity icons with the name on an activity diagramrepresent the same activity. You must add actions through the actionspecification.

Action on activities can occur of four times:

On entry

On exit

Do On event

SEQUENCE DIAGRAMS:Sequence diagram is a graphical view of a scenario that shows object

interaction in a time-based sequence. Sequence diagrams establish the rolesobjects. Sequence diagrams are normally associated with use cases.Sequence diagrams are closely related to collaboration diagrams and bothare alternate representation of an interaction.

A sequence diagram has two dimensions: typically, vertical placementrepresents time and horizontal placement represents different objects.

COLLABORATION DIAGRAMS:A collaboration diagram is an interaction diagram that shows the order

of messages that implement an operation or a transaction. Collaborationdiagrams show objects, their links, and their messages.

They can also contain simple class instances and class utility instances.Each collaboration diagram provides a view of the interactions or structuralrelationships that occur between objects and object-like entities in thecurrent model.

SCENARIOS:

Scenarios show the different sequence of interaction between actorsand system. A Scenario is an instance of a use case; it is an outline of eventsthat occur during system execution. A scenario can be expressed in text orsequence of steps.

STATE CHART DIAGRAMS:State chart diagrams model the dynamic behavior of individual classes

or any other kind of objects. They show the sequence of states that an objectgoes through, the events that cause a transition from one state to another,and the actions that result from a state change.


4/58

State chart diagrams are state centric; statement diagram is used tomodel the discrete stages of an objects lifetime.

Each state represents a named condition during the life of an objectduring which it satisfies some condition or waits for some events. A statechart diagram typically contains one start state and multiple end states.Transitions connect the various states on the diagram. Decisions,

synchronizations, and activities may also appear on state chart diagrams.

STEREOTYPES:Stereotype represents built-in extensibility mechanism for UML.Stereotype is new class of modeling element introduced during

modeling. General presentation of stereotype is string with guillemots.Various form of stereotype is

Class stereotypes

Association stereotypes

Dependency stereotypes

Component stereotypes

RATIONAL ROSE:Rational rose is a tool for understanding, analyze and designing of

software intensive system. Model in rational rose is constructed using viewsand diagrams

The views used are,

Use case view

Logical view

Component view

Development view Implementation view

Process viewRational Rose is a GUI environment containing,
