Decision support systems (DSS) are interactive computer-based systems designed to help decision makers utilize data and models to solve semi-structured or unstructured problems. There are several types of DSS including data-driven, model-driven, communications-driven, document-driven, and knowledge-driven systems. Group decision support systems (GDSS) are a specialized type of DSS that provide technology and structure to help groups make decisions and include additional capabilities to support collaboration.
