Objectives

By the end of session you will: Appreciate how a modelling approach can help a

software project Understand how a CASE tool such as Rational Rose

can support a modelling approach Be familiar with the range of different software

engineering tools in the IBM Rational Suite Be able to decide which tools might be appropriate to

your individual and team work Have an opportunity to see some of the Rational

Tools in action and discuss options for exploiting them further.

Background

Software Engineering at the School of Computing Year 1

30 Credits (300 hours) of Programming – Java Information Systems principles Human Computer Interaction design

Year 2 OO Analysis, Design and Development using UML and Java

Databases using SQL Software Engineering Project – teamwork using

Agile techniques

CASE tools

Project planning and control

Build and deploy a working system

Engineering Models

An abstraction – SHOW views of buildings Doesn’t SHOW the colour of buildings etc. Models are an Abstraction of reality

Abstraction depends on the perspective of the viewer The model builder chooses what information they consider relevant and want to communicate.

Civil engineers building a building or a bridge have to model a highly complex, interdependent, multi-layered architecture.

Civil Engineering students learning to be civil engineers need to learn how to construct and use architectural plans or blueprints.

They need to learn:

1)  Agreed standards and notation for drawing

2)  The range of Architectural views for different uses

High level and detail levels

Different views – plan, elevation etc.

Different users – electrical, plumbing, furniture

3) Computer Assisted Design (C.A.D.) Software Tools

Tools for Civil Engineers

Software engineers building a major piece of software have to model a highly complex, interdependent, multi-layered architecture.

Software Engineering students learning to be software engineers need to learn how to construct and use the equivalent of architectural plans or blueprints.

They need to learn:

1)  Agreed standards and notation for drawing 2)  The range of Architectural views for different use

3) CASE - Computer Aided Software Engineering

- make the drawing easier and

- maintain the integrity between multiple views of the same model.

Tools for Software Engineers

UML standards

Visual Model - a set of UML diagrams

Rational Rose

Rational Rose

Modelling with Rose

What modelling with Rose makes possible is

Drawing lots of UML diagrams

Keeping all these diagrams On-Line in a computer system

rather than on separate sheets of paper

The Model

The model is the collection of all the UML diagrams you create

PLUS

All the entities that appear in these diagrams

All the descriptions, details and specifications for these entities

The Next StepFrom Classes to Code

Public class Ant extends Object { // attributes private int currentPosition_X; private int currentPosition_Y;

private int direction;

private int speed;

private Boolean haveFood;

private int knownFoodPosition_X;

private int knownFoodPosition_Y;

// methods

public newAnt() {……………….};

public drawAnt() {………………};

public tellFoodLocation() { return knownFoodLocation_X;

return knownFoodLocation_Y; }

public askFoodLocation( int X, int Y) {……………..};

public moveAnt () {

if ( haveFood = True ) carryFoodToNest();

else

if ( knownFoodPosition_X > 0 and knownFoodPosition_Y > 0 )

goToFood ();

else searchForFood();

private goToFood() {…………..};

private searchForFood() {…….};

private carryFoodToNest() {….};

}

.

Ant - currentPosition_X: Integer

- currentPosition_Y: Integer

- direction: Integer

- speed: Integer

- haveFood: Boolean

- knownFoodPosition_X: Integer

- knownFoodPosition_Y: Integer

+ newAnt()

+ drawAnt()

+ tellFoodLocation()

+ askFoodLocation()

+ moveAnt()

- goToFood()

- search ForFood()

- carryFoodToNest()

Key point. The attributes translate directly. The method names translate but UML doesn’t record the

content of actual methods.

CASE Tools for TestingRational Pure Coverage

automatically evaluates the completeness of your testing and pinpoints parts of the code that are never used.

For each test it will show what what parts of the code are used and will keep track of parts of the code which have not been tested.

CASE Tools for Testing IIRational Quantify

systematically tests the performance of program code to identify bottlenecks and inefficiencies. Provides volumetric information about performance to enable detailed analysis on how software is actually working.
