Aerial Independent Models的用法和样例：
- No single model or view is sufficient. Every nontrivial system is best approached through a small set of nearly independent models with multiple viewpoints.
- The characteristics order in the dynamic maintenance model is the key of reconstruction method for history independent model.
- MDA(Model Driven Architecture) is a model-driven engineering framework to manipulate both PIMs(Platform Independent Models) and PSMs(Platform Specific Models).
- A multi-devices user interface(MDUI)model was built according to the model driven architecture(MDA), which included platform independent models(PIM)and platform specific models(PSM).
