Furthermore, what is DSS model? Decision Support Systems (DSS) are a class of computerized information system that support decision-making activities. DSS are interactive computer-based systems and subsystems intended to help decision makers use communications technologies, data, documents, knowledge and/or models to complete decision process tasks.

Keeping this in consideration, what are the major types of models used in DSS?

File drawer models are very simple models that merely present data in an organized format. Analytical models take the data and process it using a computational proves, to provide estimates the outcome of a decision.

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.
