The Model library contains functions that deal with model data and how values can be
manipulated or transformed through model entity relationships.
The Model library contains operators that create or
convert value tables using model data. Model data is necessary for directional value
transformation, to compute an entity based value, or to map values from one entity type to
another. Model data contains the information necessary to navigate from a source entity/value
to a target entity/value through the relationships defined in the model. The operators in the
model library require one or more entity tables in order to perform their function.
