Indian Railways reservation system is an example of Interactive decision support system
A decision support system (DSS) is an information system that supports business or organizational decision-making activities. DSSs serve the management, operations and planning levels of an organization (usually mid and higher management) and help people make decisions about problems that may be rapidly changing and not easily specified in advance—i.e. unstructured and semi-structured decision problems. Decision support systems can be either fully computerized or human-powered, or a combination of both.
DSS tends to be aimed at the less well structured, underspecified problem that upper level managers typically face. DSS attempts to combine the use of models or analytic techniques with traditional data access and retrieval functions. DSS specifically focuses on features which make them easy to use by non-computer-proficient people in an interactive mode. DSS emphasizes flexibility and adaptability to accommodate changes in the environment and the decision making approach of the user.
