A decision support system (DSS) is a computer-based information system that supports business or organizational decision-making activities. DSSs serve the management, operations, and planning levels of an organization (usually middle management and higher) and help people make decisions about problems that can change quickly and not be easily specified in advance, decisions and semi-structured. Decision support systems can be fully computerized, powered by people or a combination of both.
While academics have perceived DSS as a tool to support the decision-making process, DSS users see DSS as a tool to facilitate organizational processes. Some authors have extended the definition of DSS to include any system that can support decision making and some DSS include a component of decision-making software; Sprague (1980) defines a DSS proper as follows:
1. The DSS tends to be addressed to the less well-structured, unspecified problem often faced by top-level administrators;
2. DSS attempts to combine the use of analytical models or techniques with traditional data access and retrieval functions;
3. DSS specifically focuses on features that make them easy to use by people who are not computer proficient in an interactive mode; Y
4. The DSS emphasizes the flexibility and adaptability to adapt to changes in the environment and the decision-making approach of the user.
DSSs include knowledge-based systems. A properly designed DSS is an interactive software-based system to help decision-makers collect useful information from a combination of raw data, documents and personal knowledge or business models to identify and solve problems and make decisions.
Typical information that a decision support application could collect and submit includes:
• information asset inventories (including inherited and relational data sources, cubes, data warehouses and data marts),
• comparative sales figures between one period and the next,
• projected revenue figures based on product sales assumptions.
