Decision Support System (DSS)

Decision Support System (DSS) is a management information system at the level of an organization that combines data and sophisticated analytical models or data analysis tools to support the retrieval of semi-structured and unstructured. DSS is designed to help organizational decision-making. DSS is usually composed of:

1. Database (can be extracted from the Transaction Processing System / Management Information System).
2. Graphical or mathematical models, which are used for business processes.
3. User interface, which is used by the user to communicate with the DSS.
