The term “business intelligence” is synonymous with DSS The list in the following figure is an ideal set. 3- 3- Business Intelligence Proactive BI focusses on accelerating decision-making Increases information flows Five components of proactive BI: Real-time warehousing Exception and anomaly detection Proactive alerting with automatic recipient determination Seamless follow-through workflow Automatic learning and refinement 3- 3. Components of DSS Subsystems: Data management Managed by DBMS Model management Managed by MBMS User interface Knowledge Management and organizational knowledge base 3- 3- Management Subsystem Components: Database Database management system Data directory Query facility 3- 3- Database A database is a collection of interrelated data extracted from various sources, stored for use by the organization, and queried. The data from the DSS database are extracted from: Internal data, usually from TPS External data from government agencies, trade associations, market research
