**Database model** - a model (or //framework//) which runs over an observed historical period, usually with the purpose of assembling an internally-consistent historical database. Its conceptual purpose can be the same of a //calibrator// framework except that a database model is not linked to a counterpart //simulator// framework. | **Database model** - a model (or //framework//) which runs over an observed historical period, usually with the purpose of assembling an internally-consistent historical database.

**Dependency Structure** - represents the flows of information among the calculators of a framework and takes the form of an acyclic graph. The computational sequence of calculators may be inferred from the dependency structure. | **Dependency Structure** - represents the flows of information among the calculators of a framework and takes the form of an acyclic graph.
