Building Bridges
Building bridges also comprises four activities:
Specifying mapping functions
Marking the models
Verifying the mappings
Transforming the models
Specifying Mapping Functions
At this stage, on the one hand, we have a source model, and on the other, a target model that captures the abstractions that implement the concepts of the source model. The target model contains and formalizes knowledge about the target platform's structure and behavior. The problem now is to link these models together.
