MDA
- Model driven architecture effectively defines a philosophy and loose process for developing systems.
- It is model-centric, everything is a model: system, requirements, platform, the transformations that are used to move from one model to another.
- System models are separated into two parts:
- Platform independent.
- Platform dependent.
- Mappings and transformations are needed to include platform specific details - they should be modelled to.
MDA Models
PIM
- Platform Independent Model.
- Formal specifications of a system (business and service model) that abstracts away technical detail.
- e.g. a Billing System in UML.
PSM
- Platform Specific Model.
- Business and Service Model expressed in terms of the specification model of the platform.
- e.g. a Billing System expressed in UML Profile for CORBA.
Platform Model
- Model of platform component constructs e.g. of Eiffel, C#, EJB etc.
