Model management is a framework for supporting meta-data related
applications where models and mappings are manipulated as first class objects
using operations such as Match, Merge, ApplyFunction, and Compose. To demonstrate
the approach, we show how to use model management in two scenarios
related to loading data warehouses. The case study illustrates the value of model
management as a methodology for approaching meta-data related problems. It
also helps clarify the required semantics of key operations. These detailed
scenarios provide evidence that generic model management is useful and, very
likely, implementable.
