What is a model?

• A complete description of a system from a
  particular perspective Rational Unified Process

6
Why do we model?

• To manage complexity
• To detect errors and omissions early in the
  lifecycle
• To examine the relative merits of different
  options
• To communicate with stakeholders
• To drive implementation
• To understand the impact of change
• To ensure that resources are deployed efficiently

7
What is Model-Driven Development?
8
Why Model-Driven Development?

• To speed up project delivery
• In the absence of heroics, it is the fastest way
  to get from A to B
• To improve the quality of the delivered system
• Each model can act as a quality gate
• To weave together multiple stakeholder views
• Stakeholders have different, yet related,
  concerns
• To improve team working
• Models form the basis of a contract between
  project roles
• To be more efficient
• Reusing models (and model elements) throughout
  the lifecycle

Reusable Asset Specification (RAS)

• Describes the structure and nature of assets
• Reduces the friction on development
  transactions through standard, consistent
  packaging
• Each asset is described in terms of
• Classification
• Solution
• Usage
• Related Assets

Asset
Name Desc Version State Profile
29
Model-Driven Architecture (MDA)

• Model-model transformation
• E.g. Use-Case Model to Analysis Model
• Model-code transformation
• E.g. code generation, database schema generation
• Code-model transformation
• E.g. model generation from code
• E.g. visual trace
