6
Model Driven DevelopmentDelivering innovation
and collaboration
  • 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

Maybe you have to
But then, maybe you should
Well, maybe you shouldnt
7
What types of models are important?Different
Stakeholders, Different Models
  • 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
  • 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
UML The Language of Model Driven
DevelopmentStandard and extensible
  • 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

10
Challenge Manage Complexity
11
Challenge Communicate Architecture
  • Challenge
  • Overcome the problem of communicating solution to
    a team
  • 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 Discover complexity
  • Challenge
  • How can teams learn about the architecture of
    existing implementations or frameworks?
  • Resolution
  • Provide an automated means for discovering
    architecture
  • Look for Anti-Patterns
  • Visualize complexity

13
Challenge Enforce Architecture Standards
  • Challenge
  • How to enforce architecture decisions for a
    project team?
  • 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
