  5. Agenda • IBM Rational Software • Modeling • Software Development Challenges • Rational Software Architect • Demonstration • File and Directory Java exercise • Patterns • Strategy for the shell command interpreter • Composite for the directory and file • Visitor for the recursive traversal of files and directories

  6. Modeling is the standard approach in engineering to Manage Complexity Mitigate Risk Software development is the same asevery other kind of engineering in this respect Code and other artifacts can be derived from models Model Driven DevelopmentDelivering innovation and collaboration Maybe you have to But then, maybe you should Well, maybe you shouldn’t’

  7. Business Model Visualization of business processes System Architecture Model Visualization of the system requirements, structure, and behavior Use Case Model Visualization of functional requirements Analysis Model “What” the system must do to realize the functional requirements with the system What types of models are important?Different Stakeholders, Different Models • User Experience Model • Visualization of user interaction with the system • Design Model • “How” the system will realize the functional requirements • Data Model • Visualization of persistent storage • Implementation Model • Visualization of the code

  8. Model-driven development is aided by acommon language across all stakeholders Unified Modeling Language (UML) is the standard language for visualizing, specifying, constructing, and documenting the artifacts of a software-intensive system UML allows software architects, designers and developers to specify, visualize, construct, and document all aspects of a software system Extensible to support evolving modeling needs Allow expression of concepts and aspects common to industry or standard Limit modeling environment to only what is necessary UML: The Language of Model Driven DevelopmentStandard and extensible

  9. Agenda • IBM Rational Software • Modeling • Software Development Challenges • Rational Software Architect • Demonstration • File and Directory Java exercise • Patterns • Strategy for the shell command interpreter • Composite for the directory and file • Visitor for the recursive traversal of files and directories

  10. Challenge: Manage Complexity

  11. Challenge Overcome the problem of communicating solution to a team Challenge: Communicate Architecture • Resolution • Provide technologies to enable effective communication of a design • UML 2 Notation • Domain specific modeling language extensions • Integrate the architecture artifacts into the development environment • Provide Global Access to artifacts internally and for suppliers

  12. Challenge How can teams learn about the architecture of existing implementations or frameworks? Challenge: Discover complexity • Resolution • Provide an automated means for discovering architecture • Look for Anti-Patterns • Visualize complexity

  13. Challenge How to enforce architecture decisions for a project team? Challenge: Enforce Architecture Standards • Resolution • Generate source-code based on architecture decisions • Create and enforce rules which support the architecture • Process Guidance • Code rules • Visually compare model changes • Link requirements to design and to derived artifacts like code

  18. Key Feature: C/C++ Development Environment Perspective for C/C++ Development C/C++ editor with syntax highlighting, code completion, and advanced search C/C++ project hierarchical tree view UML class diagram visualization of C/C++ classes and structs

  19. Editing and Navigation C/C++ Syntax Highlighting, Outline View C++ Class Browser (Hierarchy View)‏ C/C++ Search C/C++ Content Assist Project Import Automated assistance in setting up CDT for search and content assist. UML C/C++ Code Editor Debug GDB Integrated Extensible Debug Interface Build Standard Make for projects with existing build infrastructure Managed Build Automatic makefile generation GNU tools supported out of box Managed build is extensible, build tools can be plugged-in and build tools options selectable Meets Internationalization and Accessibility requirements Extensibility Provides extension points for managed build, debuggers, … Key Feature: C/C++ Development Environment

  20. Key Feature: Modeling assistance Diagram links as first-class citizens • Simplify the capture of UML models during Analysis and Design • Make modeling more accessible to a broader audience • New custom views improve the editing experience “In diagram editing” to accelerate modeling. New “Diagram Navigator” view provides a diagram filtered view of the models and workspace Inheritance view New properties view

  21. Key Feature: Patterns Pattern rendered as a collaboration to support incremental application • Applying Patterns is very simple • Evolution of pattern experience based on lessons learned • Pattern-authoring provides greater flexibility using Open API • All Gang of Four design patterns provided • Additional patterns provided via RAS repository on IBM developerWorks Support “drag-and-drop” of pattern parameters into the collaboration New patterns view providing outline and description of the pattern
