1. A computer program product comprising one or more computer-readable media having thereon one or more computer-executable instructions that, when executed by one or more processors of a computing system, cause the computing system to instantiate an analytics-driven model view composition application that includes: a data-model binding component configured to bind model input data to one or more of a plurality of model parameters; an analytics solver mechanism configured to solve for one or more output model variables using one or more input model variables and using a plurality of analytical relationships between the plurality of model parameters; a view composition mechanism configured generate a view composition that at least in part depends on a value of the solved one or more output model variables; and a model importation mechanism configured to allow a user to import at least a portion of a pre-existing analytics-driven model into a current analytics-driven model, wherein when a portion of a pre-existing analytics-driven analytics model is imported, it supplements the plurality of model parameters with one or more additional model parameters and supplements the analytical relationships with one or more additional analytical relationships, thereby triggering the analytics solver mechanism to re-solve for model parameters within the supplemented plurality of model parameters and with the supplemented plurality of analytical relationships.
