Data-Driven DSS
Data-Driven DSS emphasize access to and manipulation of a very large time-series of data. Simple file systems accessed by query and retrieval tools provide the most elementary level of functionality. More sophisticated systems allow the manipulation and comparison of data by interactive computerized tools. Stock screening, charting and portfolio tracking are examples of Data-Driven DSS.
