| - | **Binding Variable** - A simulator variable which is linked to two different variables from the calibrator: one which is used when the model is run over simulation time, and a different one for historical time. The //History// tab of the //Variable Information// dialogue is where these links are configured. Binding variables are often base-year variables. Also note that binding variables are //fixed// - their values cannot be set from within a simulator framework - but not all //fixed// variables are binding. See the definition of //fixed// variables. | + | **Binding Variable** - A simulator variable which is linked to two different variables from the calibrator: one which is used when the model is run over simulation time, and a different one for historical time.

| **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.

| **Framework Variable** - A variable used in more than one calculator (i.e. across the framework). In model diagrams these variables are identifiable by their yellow connectivity tags. | **Framework Variable** - A variable used in more than one calculator (i.e. across the framework).
