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
