Automate my Bank !

6. Key Concept: What is Missing? What is at hand? Detail in Requirements
Domain Knowledge
Key Concept:
Automatic Code Generation = filling in for missing requirements
the less requirement details, the more automatic generation
Domain knowledge = Offering alternatives for what to fill
Variabliity= managing the offering and SELECTION of alternatives
Variability

7. Reinterpreting some Concepts
Automatic Code Generation = filling in for missing requirements
the less requirement details, the more automatic generation
Domain knowledge = Offering alternatives for what to fill
Variability= managing the offering and SELECTION of alternatives

8. Paradigm Shift From code writing to composition
Service Oriented Architecture
Software Product Lines
Component Orientation
Model Driven Development
Aspect Orientation

12. Service Oriented Architecture
SOA is usually comprised of three primary parties:
Provider (of services); basic service producers and aggregators
Requester (of services); service consumers and end users
Broker (of services); middleware, directories and registries

Enterprise(WS-BPEL,WS-Management)

18. Axiomatic Design Theory
Domain
Hierarchies
Zigzagging
Design Axioms
Axiom 1(Independence): Maintain the independence of the functional requirements
Axiom 2(Information): Minimize the information content of the design
