In respect to this, what is a model driven DSS?

Model-driven DSS include computerized systems that use accounting and financial models, representational models, and/or optimization models to assist in decision-making. Model-driven DSS use data and parameters provided by decision-makers to help in analyzing a situation, but such systems are not data intensive.

Also Know, how we can differentiate data driven DSS and model driven DSS? Both datadriven DSS and Model driven DSS are tools for information analysis. However, Model driven helps users understand the impact of decisions by providing what-if analysis whereas data driven usually analyzes developments in the past to help user make their decision.

Regarding this, what are the types of DSS?
