Service-Oriented Architecture (SOA)

• SOA Business Agility
• Business people have model of
• enterprise services
• Basic architectural building blocks
• services (e.g. web services)
• Services high level model

Model-Driven Architecture (MDA)

• OMGs MDA
• Decouple from lower level
• platforms and infrastructures
• 577a old friend Mr. TIM

• specification is over 350 pages!

SOA with MDA

• Metadata
• Foundation of both SOA and MDA
• Metadata Modeling
• UDDI
• Ineffective metadata categorization
• No broad adoption IBM, Microsoft, SAP gave up
  support
• Semantic Web
• Ontology based
• MDA uses ontology
• Ontology good for SOA

SOA with MDA

• Achieve Business Agility through Model-Driven SOA
• MDA metadata tools manage SOA service model
  meta-bus
• SOA needs manual configuration process service
  model ? implementation
• MOF (MDAs heart) transforms from PIM to PSM
• Many ontology tools, e.g. Protégé, Visio, etc
• Code generation
