What are three major components of a DSS?
Three fundamental components of a DSS architecture are:
- the database (or knowledge base),
- the model (i.e., the decision context and user criteria)
- the user interface.
What is needed for a DSS?

- Data-driven DSS. Most data-driven DSSs are targeted at managers, staff and also product/service suppliers.
- Document-driven DSS.
- Knowledge-driven DSS:
- Model-driven DSS.
What is passive DSS?
A passive DSS is a system that aids the process of decision making, but that cannot bring out explicit decision suggestions or solutions. An active DSS can bring out such decision suggestions or solutions.
Why is it so important to include a model in a DSS?
Models in DSS are generally used to analyze the situations with respect to the decision making where these models enable experimentation with different strategies under different configurations. That’s the reason why model is included in DSS.
What is the difference between MIS and information system?
Management information system (MIS) refers to a large infrastructure used by a business or corporation, whereas information technology (IT) is one component of that infrastructure that is used for collecting and transmitting data.
