1 IBM Rational Development Suite Overview Owen Johnson Information Systems Programme Manager Leeds University, School of Computing

2 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. Software Engineering

3 Agenda CASE tools at the School of Computing The Rational Suite Rational Rose – UML Modelling; Round-trip Engineering Rational Unified Process – Online methodology RequisitePro ClearCase and ClearQuest Pure Coverage and Quantify Live Demo(s) Discussion - What next

4 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

5 Engineering Models An abstraction – SHOW views of buildings Doesnt 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.

6 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

7 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

9 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

10 Class Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

11 Use Case Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

12 Activity Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

13 The Order System Model – Use Cases

14 Sequence Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

15 Collaboration Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

16 State Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

17 Component Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

18 Deployment Diagram Use Case Class Activity StateSequence Collaboration Object Component Deployment

19 The Next Step From 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() Design-level Class OOP Class (e.g. Java) Key point. The attributes translate directly. The method names translate but UML doesnt record the content of actual methods.

20 Implementation using A CASE Tool like Rational Rose Common Added Value Model Program Classes + Structure + Documentation Views & Concept Implementation Detail Round Trip Classes + Structure + Documentation

22 Order System in Visual Studio

23 Rose Views and UML Views Use Case Class Activity StateSequence Collaboration Object Component Deployment Use Cases plus Dynamic Views Logical plus Dynamic Views Note that the UML dynamic views are contained within Rose Use Case and Logical Views

24 The Rational Unified Process

25 The RUP Workflows are drawn as UML Activity Diagrams The Requirements Workflow Drill-down to deeper levels of information about the process

26 Analyse the Problem

27 Vision Artefact

28 The Vision

29 Guidelines

30 Project Management Workflow

31 RUP - Project Management Workflow

32 RUP - Project Artefacts The Key Artefacts in an RUP Project

33 RUP - Project Management Artefacts

34 Requirements Tracking Tool Requisite Pro Quick Tour – at C:\Program Files\Rational\RequisitePro\help\QuickTour.html

35 Change Request – ClearQuest Change Management – ClearCase Configuration and Change Management covers three interdependent functions

36 CASE Tools for Testing Rational 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.

37 CASE Tools for Testing II Rational 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.

38 What next? Online IBM Rational on the Web Tutorials and help files on PCs installed with Rational School of Computing, Software Engineering UML Style guidelines from Scott Ambler Reading Manuals from 2003 (in Owens office) Ambler S, The Elements of UML 2.0 Style, Cambridge University Press, 2005 Bennett S, Skelton J & Lunn K, Schaum's Outline of UML (2nd edition), McGraw-Hill, 2005 The Rational Unified Process: An Introduction, Third Edition (Paperback) by Philippe KruchtenPhilippe Kruchten Demo? Debate? OO Analysis and Design

39 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.
